I'm coding my first GAE web app in Python. I need to collect ~30 properties and instantiate a Client object (I'm using Model.db). I'd like to accomplish this on 4 separate sequential forms. If I use a separate page handler for each form, what is the best way to extract and reference the key or id on each form and put data into the same data entity? How do I avoid a global variable?
Not sure I follow... You may need to explain the issue a little more clearly.
First, do not use a global variable.
You can have 4 forms on the same template, all with the same handler. Give each a separate hidden attribute. Or, depending on your templating package, you should be able to access the form by ID.
In your handler:
entity = MyModel.get_by_key_name('my_key_name')
if request.method == 'POST':
if request.POST['hidden_field'] == 'firstform':
entity['prop_1'] = form.prop_1.data
...
if request.POST['hidden_field'] == 'secondform':
...
...
entity.put()
else:
return <template>
You will need to modify the syntax above to suit your templating pkg.

I am looking to create a feature whereby a User can download any available documents related to the item from a tab on the PDP.
So far I have created a custom record called Documentation (customrecord_documentation) containing the following fields:
Related item : custrecord_documentation_related_item
Type : custrecord_documentation_type
Document : custrecord_documentation_document
Description : custrecord_documentation_description
Related Item ID : custrecord_documentation_related_item_id
The functionality works fine on the backend of NetSuite where I can assign documents to an Inventory item. The stumbling block is trying to fetch the data to the front end of the SCA webstore.
Any help on the above would be much appreciated.
I've come at this a number of ways.
One way is to create a Suitelet that returns JSON of the document names and urls. The urls can be the real Netsuite urls or they can be the urls of your suitelet where you set up the suitelet to return the doc when accessed with action=doc&id=_docid_ query params.
Add a target <div id="relatedDocs"></div> to the item_details.tpl
In your ItemDetailsView's init_Plugins add
$.getJSON('app/site/hosting/scriptlet.nl...?action=availabledoc').
then(function(data){
var asHtml = format(data); //however you like
$("#relatedDocs").html(asHtml);
});
You can also go the whole module route. If you created a third party module DocsView then you would add DocsView as a child view to ItemDetailsView.
That's a little more involved so try the option above first to see if it fits your needs. The nice thing is you can just about ignore Backbone with this approach. You can make this a little more portable by using a service.ss instead of the suitelet. You can create your own ssp app for the function so you don't have to deal with SCAs url structure.
It's been a while, but you should be able to access the JSON data from within the related Backbone View class. From there, within the return context, output the value you're wanting to the PDP. Hopefully you're extending the original class and not overwriting / altering the core code :P.
The model associated with the PDP should hold all the JSON data you're looking for. Model.get('...') sort of syntax.
I'd recommend against Suitelets for this, as that's extra execution time, and is a bit slower.
I'm sure you know, but you need to set the documents to be available as public as well.
Hope this helps, thanks.
In my Fusion Web Application, I have defined several business rules in entity objects. Everything works fine. The problem is that I can not get them programatically. I have searched through the EntityObjects Impl java class, but there is no method that should perform validation. Does anyone know any way, how to get the business rules from an entity object? I need to get at least a list of those.
Update:
EntityDefImpl eoDef = EntityDefImpl.findDefObject("package...MyEO");
for (Object o : eoDef.getValidators()) {
System.out.println("Rule: " + o);
}
But even in this case, I do not get a list of business rules.
Try the following instead of your implementation
EntityDefImpl eoDef = EntityDefImpl.findDefObject("package...MyEO");
AttributeDefImpl myAttribute=getAttributeDefImpl("MyAttribute"); //Get the first Attribute
for (Object o : myAttribute.getValidators()) {
System.out.println("Rule: " + o);
}
The one you did will get the Entity level validators only, this one will get you this specific attribute validators!
Take a look at the EntityDefImpl class. Since it applies to all EO instances it carries the validation.enter link description here
If you just want to call it, you can use the Validate function from ViewObjectImpl (Since you want to call it from the Web Application programmatically or your Application Module)
If you want to add another Validation, then you should follow the first answer.
For example I have a wpf window bound to an customer Entity (let suppose it's cus1). Then I load another entity from context :
customer cus2 = context.customers.where(x=>x.id=10).FirstOrDefault();
Now I want cus1 = cus2 ? I can do this way :
cus1.name = cus2.name;
cus1.address = cus2.address;
...
...
This way meets my case (the content of textboxs in the form change immediately into values of cus2) but I wonder if there is anyway to make it shorter since cus1=cus2 doesn't work ?
Thanks
You can use the memberwise Clone method to make a shallowcopy of a business object:
See http://msdn.microsoft.com/de-de/library/system.object.memberwiseclone.aspx
You could also use Serialization or Reflection, to do it on your own. However both oof the methods are slower then writing it directly.
Take a look at this article. Maybe you will find it helpful:
http://www.codeproject.com/KB/dotnet/CloningLINQ2Entities.aspx
Edit:
Btw. Remember, using using MemberwiseClone, in case of ReferenceTypes will effect in copying the references, not objects.
If you want to update the values of a Customer entity in memory with the newest values in the datastore you can use the Refresh method on your ObjectContext.
Here is the documentation.
In your case it would look like:
context.Refresh(RefreshMode.StoreWins, cus1);
If you really want to map two entities you could have a look at AutoMapper. AutoMapper will help you by automatically mapping entities to each other with a default setup that you can tweak to your needs.
I have a multi-domain site. Depending on the domain the site needs to behave accordingly.
I created a helper called CompanyInfo it has methods such as name(), phone(), email(), etc.
Depending on what domain you are on it returns the correct information.
So for example if I need to display the phone number for a user to call I would use $this->CompanyInfo->phone() and it will display the correct phone number for the user depending on the domain.
Ok, this is all good, but not really relevant. The real issue is, I need this information in more than just the view. Helpers are just for views though. If I want to access this information from a controller I need to create a component to do it.
I really don't want to have a Helper and a Component doing the same thing. I would rather have one class handle it rather than copy and paste logic.
So whats the best way to have a class with methods that can be accessed from the controller or view or even model?
Is it just this kind of static information (name, phonenumber, email, etc) what you need to display? Why not just add them to your configuration in core.php?
Something like
# in core.php
Configuration::write('Company.name', 'Acme Corp.');
Configuration::write('Company.email', 'joe#acme.com');
You can then get this info anywhere you need using
Configuration::read('Company.name');
You can define this variable in your app_controller and then use these variable easily in any of your controller as set these variables from there only.
Call this function in your construct class.
i think that will solve your problem.
You can access model classes from any place this way :
$companyInfoModel = ClassRegistry::init('CompanyInfo');
$phone = $companyInfoModel->phone();
a) you can use libs in cake1.3 for that
b) static model methods which you can pass the content to and which will return the expected value
echo Model::phone($data)
Is it possible to save ModelForm object data with db_alias different than "default"
my_form = MyModelForm(request.POST)
my_form.save(commit=True,using="db_alias")
as well as saving data with model instance?
Thank you.
Short Answer: Unfortunately ,you can't save the form that way. If you form doesn't contain ForeignKey or m2m fields (or you are controlling them yourself, for example using an autocompletefield, etc.), you can handle the object after the form:
_obj = _form.save(commit=False)
_obj.save(using=_db_alias)
Long answer: If you want the modelform to behave like a normal one with ForeignKeys and m2m-fields, something like:
# The form's foreign_keys and m2m-fields get the data from the db_alias database
# and evertyhing is sdisplayed correctly on the template.
_form = myModelForm(request, db_alias=_db_alias)
# The form saves to the correct DB and foreigns & M2ms are matched correctly in this DB
# _form.save()
Although this would be ideal, you just can't use this behaviour. There are many DB hooks that you need to alter in Django code to get this working. What I have done is to create a new modelform class from the base modelform, and get the (partial) functionality described before.
Hope this helps, and also hopping a better solution comes soon.
