Task: I would like to catch data sending by flask-admin to database after fill in forms in admin panel.
I have overridden default User view as follows:
from flask_admin.contrib.sqla import ModelView
class UserModelView(ModelView):
def is_accessible(self):
return current_user.is_active and current_user.is_authenticated and current_user.has_role("admin")
def _handle_view(self, name, **kwargs):
if not self.is_accessible():
return redirect(url_for("admin.index"))
All modifications on admin panel after save are going to database (flask-sqlalchemy) and it works fine.
Now I would like to catch the data that is sending, for example:
I have changed username from X to Y and click "save".
I want to catch that piece of information with username = "Y" sending to database.
In docs I saw that there is method:
on_model_change(form, model, is_created)[source]
Perform some actions before a model is created or updated.
So I think this is a place where I should put my code, but question is, how can I get that data sending from there to database?
Normally, when I fill in something on web, its form defined by me so I just use data from this form, but here its defined by flask-admin and I have to idea how to access there.
Any ideas?

I have just started working on Django, angularjs , The issue currently i am facing is I have created a model in django as following
**class Car_Booking(models.Model):
owner = models.ForeignKey('auth.User', related_name='booking_user')
car_id=models.IntegerField(max_length=4,default=1)
extra_field1=models.CharField(max_length=100,null=True)
extra_field2=models.CharField(max_length=50,null=True)
extra_field3=models.CharField(max_length=50,null=True)**
The Serializer is as following
**class CarBookingSerializer(serializers.HyperlinkedModelSerializer):
owner = serializers.ReadOnlyField(source='owner.username')
class Meta:
model = Car_Booking
fields = ('car_id','owner','extra_field1','extra_field2','extra_field3')**
And view is as following
**class CarBookingViewSet(viewsets.ModelViewSet):
"""
This viewset automatically provides `list`, `create`, `retrieve`,
`update` and `destroy` actions.
Additionally we also provide an extra `highlight` action.
"""
queryset = Car_Booking.objects.all()
serializer_class = CarBookingSerializer
permission_classes = (permissions.AllowAny,
def perform_create(self, serializer):
serializer.save(owner=self.request.user)**
Now i developed a front end on Angularjs, the templelates i built were on the same server say localhost:8000 so when i call the view to insert the data by passing car_id, extra_field1, extra_field2 and extra_field 3 it gets saved successfully because i already get logged in and saved the user information into the cookies so i guess the Owner field is resolved automatically. Now when i call the same view from the IONIC framework on server localhost:5000(port is differnt) it give me the error, "Owner must be a user instance". I have searched a lot but can not find how to send the user authentication information, or save it accross the domains. Secondly i have tried to pass the owner_id but when i write the owner_id into the serializer it says "Owner_id is not a valid modlebase" but while calling throught the command prompt i can set the owner_id, Any Help on the following questions
***1. How can i send the username and password along the Post URL
How can i set the owner_id instead of OWNER object instance.***

So I have an app that takes a form, and sends and e-mail address to somebody, but I want a way to stick and activation URL generated by Django into that e-mail, and not have the form data commit to the database until that activation link is clicked. Is there any way to do this?
Based on the comments on my first answer, here's a reworked one more suited to your needs.
Create a model, e.g. ServiceHours, that next to the data you want to collect (hours done, supervisor_email, ...), has the following fields:
activation_key=models.CharField(_('activation key'), max_length=40, null=True, blank=True)
validated=models.BooleanField(default=False)
I'd suggest adding a post_save signal to the Model, so that whenever a new ServiceHours instance is created (by saving the form), the email to the supervisor is sent.
# Add this to your models file
# Required imports
from django.db.models.signals import post_save
from django.utils.hashcompat import sha_constructor
import random
def _create_and_send_activation_key(sender, instance, created, **kwargs):
if created: # Only do this for newly created instances.
salt = sha_constructor(str(random.random())).hexdigest()[:5]
# Set activation key based on supervisor email
instance.activation_key = sha_constructor(salt+instance.supervisor_email).hexdigest()
instance.save()
# Create email
subject = "Please validate"
# In the message, you can use the data the volunteer has entered by accessing
# the instance properties
message = "Include instance hours, volunteer's name etc\n"
# Insert the activation key & link
messsage += "Click here: %s" % (reverse("validate_hours", kwargs={'id': instance.id, 'activation_key':instance.activation_key})
# Send the mail
from django.core.mail import send_mail # Move this import to top of your file ofcourse, I've just put it here to show what module you need
send_mail(subject, message, sender, recipients)
post_save.connect(_create_and_send_activation_key, sender=ServiceHours)
Define a view to validate service hours based on an activation key
# in views.py
def validate_hours(request, id, activation_key):
# find the corresponding ServiceHours instance
service_hours = ServiceHours.objects.get(id=id, activation_key=activation_key)
service_hours.validated = True
service_hours.save()
In your urls.py, define an url to your validate_hours view:
urlpatterns += patterns('',
url(r'^validate-hours/(?P<id>[0-9]+)/(?P<activation_key>\w+)', validate_hours, name='validate_hours'),
This has all been off the top of my head, so please excuse any errors. I hope you get the gist of the process and can extend according to your exact needs.
You might want to set/unset the is_active flag on the user.
Conceptually:
When a user registers succesfully, be sure to set the flag to False;
Autogenerate a unique string that is tied to the user's ID and send the activation url via email;
In the activation view, decompose the key into the user ID and set the is_active flag to True;
In your login view, check whether the user trying to log in has is_active is True.
Then you'll be sure that users who are logged in have a confirmed email address.
The page in Django's documentation on user authentication provides all necessary information. For a sample login view, the chapter "How to log a user in" has one.
If you'd prefer to use a reusable app, django-registration might fit your needs perfectly.
(Post-reply addition:) why not commit the data to the database? The "waste" of having unactivated users residing in your database does not outweigh the effort you'd need to implement a solution that does not commit the data to the database. Moreover, it might be more than interesting to have an idea of the amount of unactivated users (and act accordingly).
I need to update info of an existing user in my database programmaticaly
I need to update user name birth date values in user_ table in Liferay database
basically I need to run an update query.
It is not recommended to update the liferay database directly, you should use Liferay API instead to do these things. As per this liferay forum post:
The Liferay database is not published for a reason. The reason is the API does significantly more stuff than just simple SQL insert statements. There are internally managed foreign keys, there are things which are updated not just in the database but also in the indices, in jackrabbit, etc.
Since all of this is managed by the code and not by the database, any updates to the code will change how and when the database is updated. Even if it did work for you in a 6.1 GA1 version, GA2 is coming out in a couple of weeks and the database/code may change again.
Sticking with the API is the only way to insure the changes are done correctly.
Ok enough preaching and back to your problem, here are some ways you can do these:
you can either build a custom portlet and use liferay's services and update the username, birthdate etc using UserLocalServiceUtil.updateUser() method.
Or you can build a web-service client based on SOAP or JSON to update the details which would call the same method
Or you can use Liferay's Beanshell tool to do this from the control panel, following is some code to update the user (created just for you ASAP):
import com.liferay.portal.model.Company;
import com.liferay.portal.model.Contact;
import com.liferay.portal.model.ContactConstants;
import com.liferay.portal.model.User;
import com.liferay.portal.service.CompanyLocalServiceUtil;
import com.liferay.portal.service.ContactLocalServiceUtil;
import com.liferay.portal.service.UserLocalServiceUtil;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
long companyId = 10135; // this would be different for you
User user = UserLocalServiceUtil.getUserByEmailAddress(companyId, "test#liferay.com");
// Updating User's details
user.setEmailAddress("myTest#liferay.com");
user.setFirstName("First Test");
user.setLastName("Last Test");
user.setScreenName("myTestScreenName");
UserLocalServiceUtil.updateUser(user, false);
// Updating User's Birthday
// December 12, 1912
int birthdayMonth = 11;
int birthdayDay = 12;
int birthdayYear = 1912;
Calendar cal = new GregorianCalendar();
cal.set(birthdayYear, birthdayMonth, birthdayDay, 0, 0, 0);
cal.set(Calendar.MILLISECOND, 0);
Date birthday = cal.getTime();
System.out.println("Updated User: " + user + "\nBirthdate to be updated: " + birthday);
long contactId = user.getContactId();
Contact contact = ContactLocalServiceUtil.getContact(contactId);
if(contact == null) {
contact = ContactLocalServiceUtil.createContact(contactId);
Company company = CompanyLocalServiceUtil.getCompany(user.getCompanyId());
contact.setCompanyId(user.getCompanyId());
contact.setUserName(StringPool.BLANK);
contact.setCreateDate(new Date());
contact.setAccountId(company.getAccountId());
contact.setParentContactId(ContactConstants.DEFAULT_PARENT_CONTACT_ID);
}
contact.setModifiedDate(new Date());
contact.setBirthday(birthday);
ContactLocalServiceUtil.updateContact(contact, false);
System.out.println("Users birthdate updated successfully");
The contact code is built with the help of Liferay's source code for UserLocalServiceImpl#updateUser method
In case you are wondering what is bean-shell and where to put this code, here is where you can find it in Liferay Control Panel Control Panel --> Server --> Server Administration --> Script
It depends on whether you have to do this in a portlet code or by sending a direct query to db.
Liferay basically caches everything, so if you update a record in the Liferay database while the portal is running, most likely that record is already in cache, and so the new column values won't be read at all. You will have to clear the database cache by going to Control Panel -> Server Administration.
On the contrary, if you have to do such a thing in a portlet code, you should call one of the methods of the Liferay services. You're trying to update a User, so you should call the method UserLocalServiceUtil.updateUser (or UserServiceUtil.updateUser if you also want to check permissions).
You can see there are some different updateUser methods, one of them has a lot of parameters and another has only the bean as a parameter. While the first one contains all the business logic (validation, reindexing, update of related entities, etc.), the second one was just autogenerated and should not be used (except when you absolutely know what you're doing). So, use the method with a lot of parameters, simply passing user.getCOLUMN() (eg. user.getFacebookId()) if you don't want to change the value of that column.
Hope it helps, and sorry for my bad English...
update user_ set firstName="New First Name", lastName="New Last Name" where emailAddress="test#test.com";
update contact_ set birthday="date string" where contactId in(select contactId from user_ where emailAddress="test#test.com");
By first update query you can change firstName, lastName of user and by second query you can change birthdate of user.
Hope its clear!
Try this code..
Here i am updating only user First name(rest you can do by your own way)
userId = you can get this using theme display
User user = UserLocalServiceUtil.getUser(userId);
user.setFirstName("new name");
UserLocalServiceUtil.updateUser(user);
Hope this will help you !!!
i have a simple question. if i use play.db.ebean.Model to have my Model extend from Model, how can i save it into DB? more clearly: in Django, the database file is created and i save the object, it will be saved into db file and i dont do any sql statements for retrieving or saving objects.. how does this work in playframework?
lets say i have configured my database file in application.conf file like this:
db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:tcp://localhost/~/microblogdb"
db.default.user="sa"
db.default.password=""
now i have a database file somewhere in system.
now i have a Class User which extends Model as i stated above. now i want to save one User object into db. so i will do like this:
User user = new User();
user.username = "testusername";
user.fullname = "userfullname";
user.save();
what will happen after that save() call? can i now directly see my User object in database file?
appreciate any help!
many thanks
Yes it will, if you didn't do any mistakes.
Make sure that in application.conf you also UNcommented the line:
ebean.default="models.*"
Check sample applications in sample folder of the Play package you downloaded. For an example ComputerDatabase (not JPA version) to see the basics of working with Ebean.
What's more you can create constructor(s) in your model to simplify creating User model:
public User(String username, String fullname) {
this.username = username;
this.fullname = fullname;
}
And use it in controller as:
User user = new User("doniyor", "Doniyor The Great");
user.save();
today i tried to get django-piston and ExtJS working. I used the ExtJS restful example and the piston example to create a little restful webapp. Everything works fine except the authentication.
Whats the best way to get Basic/Digest/OAuth authentication working with ExtJS?
Atm I'm not sure where to set the Username/Password.
Thanks
If you want to use piston with ExtJS, I would suggest writing an anonymous handler that checks the user is logged in via standard auth.
Try this:
class AnonymousUserProfileHandler(BaseHandler):
fields = ('title', 'url', 'affiliation')
model = UserProfile
def read(self, request, nickname):
profile = UserProfile.objects.get(nickname=nickname)
if request.user == profile.user:
return profile
class UserProfileHandler(BaseHandler):
anonymous = AnonymousUserProfileHandler
allowed_methods = ('GET')
fields = ('title', 'url', 'affiliation')
model = UserProfile
def read(self, request, nickname):
profile = UserProfile.objects.get(nickname=nickname)
return profile
In this example, when UserProfileHandler is called, without any authorization, it delegates to the anonymous handler. The anonymous handler checks whether the user is logged in via the usual request.user mode. If there is a valid user, it returns their profile object. You would then, obviously, mark the view calling this as requiring login.
The point is: when extJS makes its JSON call, it will send authentication data via the usual cookie. If you use an "anonymous" handler in Piston, but manually check the user is logged in before returning the data, then you essentially use traditional auth for your own site.
