django multiple form separated in the html, merge again with submit
there is a formmodel like: class foo(forms.ModelForm): a = forms.BooleanField(label='a', required=False) b = forms.BooleanField(label='b', required=False) c = forms.BooleanField(label='c', required=False) d = forms.BooleanField(label='d', required=False) e = forms.BooleanField(label='e', required=False) f = forms.BooleanField(label='f', required=False) g = forms.BooleanField(label='g', required=False) h = forms.BooleanField(label='h', required=False) #... further there are multiple instances of foo in a list: L = [] L.append(foo(instance=object_1)) L.append(foo(instance=object_2)) L.append(foo(instance=object_3)) #... L.append(foo(instance=object_n)) this is shown on the html in different tables in different columns. The problem now is to send the data back correctly with subbmit. I have to put the tables and lines back together correctly.

Django correct way to place form in template
this is my test model form class FieldForm(forms.ModelForm): class Meta: model = Field fields = ( 'title', 'url', ) It has two fields but for design reasons I need each input in a seperate DIV in the template like so (just an example) <form> <div> <input spellcheck="false" autocorrect="off" type="email" required="" name="re_email"> </div> <div> <input spellcheck="false" autocorrect="off" type="email" required="" name="re_email"> </div> </form> When I just add {{ form }} every input is in the form without a surrounding container.

Can I override default CharField to ChoiceFoeld in a ModelForm?
I have a (horrible) database table that will be imported from a huge spreadsheet. The data in the fields is for human consumption and is full of "special cases" so its all stored as text. Going forwards, I'd like to impose a bit of discipline on what users are allowed to put into some of the fields. It's easy enough with custom form validators in most cases. However, there are a couple of fields for which the human interface ought to be a ChoiceField. Can I override the default form field type (CharField)? (To clarify, the model field is not and cannot be constrained by choices, because the historical data must be stored. I only want to constrain future additions to the table through the create view). class HorribleTable( models.Model): ... foo = models.CharField( max_length=16, blank=True, ... ) ... class AddHorribleTableEntryForm( models.Model) class Meta: model = HorribleTable fields = '__all__' # or a list if it helps FOO_CHOICES = (('square', 'Square'), ('rect', 'Rectangular'), ('circle', 'Circular') ) ...? -

Conditional query in django [closed]
Am worried that it may cause any problem, as am using conditional querying paramters. Here is my query: data = Project.objects.filter(user=user if user.role == 1 else user.staff_to_id) In this, staff_to_idis just a self reference to a user to represents that this is a staff. So if Role == 1 then Projects will be fetched using "user" and when Role == 2 or something else it will Project will be fetched using "user.staff_to_id" Is this a bad practice ? -

Django: Create a Model from parsing a different model's field
I have a model A with several fields. One of the fields ("results") is a a dict-like string in my database (which is hardly readable for a human being). Can I create a separate Model that would basically parse that "results" field into its own fields, so I can have a separate table with fields corresponding to the keys and values from my "results" field from model A? Final goal is to make a Results table that shows all the information in a pretty and easy-to-read manner. class ModelA(models.Model): language = models.CharField(max_length=30) date = models.DateTimeField() results = models.CharField(max_length=255) This is how "results" field looks in my database (I cannot change this format): OrderedDict([('Name', 'Bob'), ('Phone', '1234567890'), ('born', '01.01.1990')]) I want to create something like this: class Results(models.Model): name = model.Charfield(max_length=100) phone= model.IntegerField() born = model.DateTimeField() What is the best way to do this? How do I take the info from the "results" field from ModelA and "put" it into the Results model? -
