Django partial update without form submission -

I'm using Django to write an application that will have an interface for automatic requests and similar, which As a graphical / HTML UI now, I will use

  POST / addFoo? A = 1 & amp;  ModelForm  to request such requests like  Hello  > 
 
 
  
 Forms will be added to the database and the form flico (): fu = form.save () returns successful (id = foo.id) if ff for (request) form FIF (request):  
  Def addFoo (request) Other: Correct fail (code = 0, error = form. Errors)   
 Where  successful  and  fail  are appropriate There are functions to generate feedback / Rves entries this part, however, works fine, I would write a similar function  editFoo  so if the ID of any object 1,  
  POST / editFoo? Id = 1 & amp; A = 42   
 will change the  a  field of that object to 42. View function like I currently have  
  def editFoo (request :): try: except foo = models.Foo.objects.get (id = request ['id']): Return If form.is_valid (): form.save () return successful () other: failed to fail (code = 0, error = u'No such object does not exist! ') Form = FooForm (request, example = Foo) 1, error = form.errors)   
 However, when I test this, the unspecified areas which contain error messages in Form.errors are required. Since these requests will be initiated by the client (i.e. I can not pre-load an HTML  & lt; form & gt;  to edit them), I can not find any way to do this  
 Edit: Models and forms are really simple:  
  square fu (model): a = integerfilled () b = four variables (max_lamb = 23 )   
 and  
  class FooForm (ModelForm): Class Meta: Model = Foo    
 
 
 You will need to use LA which will only contain fields that you are expecting  
  class FooEditForm (ModelForm):   
: Class = Meta: Model = Foo Field = ('A',)   
 Allow field to be omitted:  
  class FooEditForm (ModelForm): square meta: model = foo A = form. Integerfield (required = false)   
     Code> Category FooEditForm (ModelForm): Square Meta: Model = Foo def __init __ (Self, * args, ** kwargs): Super (FooEditForm, Self) .__ init __ (* Args, ** kwargs) in the field in self.fields. Itervalues ​​(): field.required = False
