I have these models:
CURSES=(('python','Python'),('django','Django'),...)
class Asig(models.Model):
...
name = models.CharField(max_length=100, choices=CURSES)
class Profesor(AbstractUser):
...
asigs = models.ManyToManyField(Asig)
Then, when I render the form using ModelForm the many-to-many field shows itself with 'python' string instead 'Python', also, when I look the rendered html coded the multiselect options look like:
<option value='1'>python</option>
instead of
<option value='python'>Python</option>
If you want to use the value 'Python' in the model's __str__, method, then you should use self.get_name_display() instead of self.name:
class Asig(models.Model):
...
name = models.CharField(max_length=100, choices=CURSES)
def __str__(self):
# use @python_2_unicode_compatible or define __unicode__ if using Python 2
return self.get_name_display()
You can't easily change many-to-many field to use value='python' instead of value='1' (the primary key). That's just the way many-to-many fields work.
