I hope I'm wrong, but it looks to me like the only way to have no help_text for a ManyToManyField is write an __init__ method for the form and overwrite self.fields[fieldname].help_text. Is that really the only way? I prefer to use CheckboxSelectMultple widgets, so am I really going to have to define an __init__ method for any form that uses a ManyToManyField?
class ManyToManyField(RelatedField, Field):
description = _("Many-to-many relationship")
def __init__(self, to, **kwargs):
#some other stuff
msg = _('Hold down "Control", or "Command" on a Mac, to select more than one.')
self.help_text = string_concat(self.help_text, ' ', msg)

A ManyToMany field is used when a model needs to reference multiple instances of another model. Use cases include: A user needs to assign multiple categories to a blog post. A user wants to add multiple blog posts to a publication.
In order to make a field optional, we have to say so explicitly. If we want to make the pub_time field optional, we add blank=True to the model, which tells Django's field validation that pub_time can be empty.
Django Model Form It is a class which is used to create an HTML form by using the Model. It is an efficient way to create a form without writing HTML code. Django automatically does it for us to reduce the application development time.
class Item(models.Model):
...
category = models.ManyToManyField(Category, null=True,blank=True)
category.help_text = ''
...
In a regular form:
MyForm.base_fields['many_to_many_field'].help_text = ''
If you want to change the (i18n) string:
class MyForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__( *args, **kwargs)
self.base_fields['many_to_many_field'].help_text = _('Choose at least one stuff') # or nothing
Tested with django 1.6
