I want to show the Django choice field from Model on the HTML template like in the following picture. I can't see anything after doing this code.
models.py
class Author(models.Model):
TITLE_CHOICES = [
('MR', 'Mr.'),
('MRS', 'Mrs.'),
('MS', 'Ms.'),
]
title = models.CharField(max_length=3, choices=TITLE_CHOICES)
views.py
def AuthorView(request):
form = Author(request.POST or None)
title = Author.objects.all()
context = {
"form": form,
"ttile": title,
}
if form.is_valid():
form.save()
return render(request, 'index.html')
return render(request, 'index.html', context)
index.html
<select name="confirm_type" id="confirm_type">
{% for object in ttile %}
<option value="by_email"> {{ object }} </option>
{% endfor %}
</select>

PLEASE I NEED HELP ON SOME OF THESE QUESTIONS BELOW:
How can l write that validation error in django validators.py?
Where did i made a mistake aand how to solve it
I am trying to comment in a room but anytime I commented a Non NUll constrained error raised and I cannot find the problem.
The models are as follows:
class Room(models.Model):
host = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
topic = models.ForeignKey(Topic, on_delete=models.SET_NULL, null=True)
name = models.CharField(max_length=200)
description = models.TextField(null=True, blank=True)
updated = models.DateTimeField(auto_now=True)
created = models.DateTimeField(auto_now_add=True)
class Meta:
ordering = ['-updated', '-created']
def __str__(self):
return self.name
class Message(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
room = models.ForeignKey(Room, on_delete=models.CASCADE)
body = models.TextField()
updated = models.DateTimeField(auto_now=True)
created = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.body[0:50]
The views is as follows:
def room(request, pk):
room = Room.objects.get(id=pk)
room_messages = room.message_set.all().order_by('-created')
if request.method == 'POST':
message = Message.objects.create(
user=request.user,
room=room,
body=request.POST.get('body')
)
return redirect('room', pk=room.id)
context = {
'room': room, 'room_messages':room_messages
}
return render(request, 'base/room.html', context)
The html:
{% if request.user.is_authenticated %}
<div class="comment-form">
<form method="POST" action="">
{% csrf_token %}
<!-- {{form}} -->
<input type="text" name="comment" placeholder="Write your message here..."/>
</form>
</div>
{% endif %}
{% endblock content %}
Thank you. I found out that in the html I've assigned "comment" instead of "body" to the name=''" in the input tag.
I'm new at GAE and all that python stuff, so question might be stupid at last.)
I have model:
from google.appengine.ext import db
class Task(db.Model):
name = db.StringProperty()
summary = db.StringProperty(multiline=True)
and I want to auto generate form, so:
import webapp2
import jinja2
import os
from wtforms.ext.appengine.db import model_form
from Tasks.model import Task
jinja_environment = jinja2.Environment(
loader=jinja2.FileSystemLoader(os.path.dirname(__file__) + '/../templates/admin'))
class AddTaskPage(webapp2.RequestHandler):
def get(self):
AddForm = model_form(Task)
template_values = {
'form_self_link': self.request.path,
'form_content': AddForm
}
template = jinja_environment.get_template('add_task.html')
self.response.out.write(template.render(template_values))
add_task.html template:
<form method="POST" action="{{form_self_link}}">
{{form_content}}
<input type="submit" value="Add">
</form>
And the most confusing is output –
<form method="POST" action="/admin/tasks/add">
<class 'wtforms.ext.appengine.db.TaskForm'>
<input type="submit" value="Добавить">
</form>
There is NO form's elements, there is just very strange <class 'wtforms.ext.appengine.db.TaskForm'> stuff.
I use GAE 1.6.1, python 2.7.2, jinja 2.6 (bundled with GAE), WTForms 0.6.3 (latest)
Could you please help?
UPDATE:
I've used instruction bundled with class and it is not working:
from google.appengine.ext import db
from tipfy.ext.model.form import model_form
# Define an example model and add a record.
class Contact(db.Model):
name = db.StringProperty(required=True)
city = db.StringProperty()
age = db.IntegerProperty(required=True)
is_admin = db.BooleanProperty(default=False)
new_entity = Contact(key_name='test', name='Test Name', age=17)
new_entity.put()
# Generate a form based on the model.
ContactForm = model_form(Contact)
# Get a form populated with entity data.
entity = Contact.get_by_key_name('test')
form = ContactForm(obj=entity)
The only strange moment is "from tipfy.ext.model.form import model_form" string, but I think it is just an error in docs.
UPDATE 2
Well I managed to get it work and may be I missed something, seems like there is no feature "auto print form" in WTForm. So it works now like that:
class AddTaskPage(webapp2.RequestHandler):
def get(self):
AddForm = model_form(Task)()
template_values = {
'form_self_link': self.request.path,
'form_name_field': AddForm.name
}
template = jinja_environment.get_template('add_task.html')
self.response.out.write(template.render(template_values))
And prints out
<form method="POST" action="/admin/tasks/add">
<input id="name" name="name" type="text" value="">
<input type="submit" value="Добавить">
</form>
Well... seems like the only option is to do something like in future (taken from docs)
<form method="POST" action="/...">
<div>{{ form.username.label }}: {{ form.username(class="css_class") }}</div>
<div>{{ form.password.label }}: {{ form.password() }}</div>
<!-- and so on .... -->
</form>
Is it really no any auto-generate and auto-print form libraries for GAE with Python 2.7?(
LAST UPDATE
Well... I found one option to get it work and render all form elements:
class AddTaskPage(webapp2.RequestHandler):
def get(self):
addForm = model_form(Task)()
template_values = {
'form_self_link': self.request.path,
'form': addForm
}
template = jinja_environment.get_template('add_task.html')
self.response.out.write(template.render(template_values))
def post(self):
addForm = model_form(Task)(self.request.POST)
template_values = {
'form_self_link': self.request.path,
'form': addForm
}
template = jinja_environment.get_template('add_task.html')
self.response.out.write(template.render(template_values))
In template:
{% for field in form %}
<tr>
<th>{{ field.label }}</th>
<td>{{ field }}</td>
</tr>
{% endfor %}
Looks not so bad .)
I think you have to pass AddForm.content as a template value (instead of AddForm)
template_values = {
'form_self_link': self.request.path,
'form_content': AddForm**.content**
}
UPDATE
found this in the docs
(http://wtforms.simplecodes.com/docs/0.6.1/ext.html#wtforms.ext.appengine.db.model_form)
wtforms.ext.appengine.db.model_form(model)
Creates and returns a dynamic wtforms.Form class for a given db.Model class. The form class can be used as it is or serve as a base for extended form classes...
So what you are passing into the template is the class, not an instance of it.
AddForm = model_form(Task)()
I did everything specified in the documentation of app engine but i couldn't get the blobstore work. Maybe some of you can detect what i am doing wrong. When i clicked the submit button
This kind of a url is seen in the address bar and an empty white page is in front of me.
http://localhost:8080/_ah/upload/agltb2JpbHNvcnVyGwsSFV9fQmxvYlVwbG9hZFNlc3Npb25fXxg9DA
Does anyone have a suggestion?
These are my Handlers :
class MainHandler(webapp.RequestHandler):
def get(self):
years = Years.all().order("Year")
months = Months.all().order("SortNumber")
upload_url = blobstore.create_upload_url('/imidergi/upload')
content = {
'upload': upload_url,
'yearList':years,
'monthList':months,
}
render_template(self, 'imidergi.html', content)
class AddDergi(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
# 'file' is file upload field in the form
upload_files = self.get_uploads('file')
blob_info = upload_files[0]
dergi = Dergiler()
dergi.Year = self.request.get("yil")
dergi.Month = self.request.get("ay")
dergi.DergiPDF = str(blob_info.key())
dergi.Name = self.request.get("isim")
dergi.Image = self.request.get("resim")
dergi.put()
self.response.out.write(dergi.Name)
And this is the html which renders the form.
<form action="{{ upload }}" method="post" id="dergiform" enctype="multipart/form-data">
{{ upload }}
<label>Yil:</label><select name="yil">
{% for year in yearList %}
<option value="{{ year.Year }}">{{ year.Year }}</option>
{% endfor %}
</select><br/>
<label>Ay:</label><select name="ay">
{% for month in monthList %}
<option value="{{ month.Name }}">{{ month.Name }}</option>
{% endfor %}
</select><br/>
<label>Isim: </label><input type='text' id="isim" name="isim"/><br/>
<label>Dergi: </label><input type='file' id="file" name="file"/><br/>
<label>Resim: </label><input type='file' id="resim" name="resim"/><br/>
<label></label><input type='submit' value='Ekle'/>
</form>
IIRC BlobstoreUploadHandler expects you to return a redirect after you have handled the POST as your handler is really responding to the special BlobStore upload servers and not directly with the client/browser like in a normal request.
Copy the example from the blobstore docs, and remember that you can only respond with headers (like redirects) and not with body content.
