Generator to help make newforms classes a bit like inspectdb does for generating rough model code. This is a standalone script to go in your project directory with settings.py and called from the prompt. It looks up the model, and generates code to copy/paste into your app. Hopefully to make a building a custom form with a lot of fields a little easier. Every argument should be a model identifier of form appname.modelname.
Usage from the command line:
python form_gen myapp.MyModel myapp.MyOtherModel
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 | #!/usr/bin/python
import sys, os
import datetime
from django.core.management import setup_environ
import settings
project_directory = setup_environ(settings)
project_name = os.path.basename(project_directory)
os.environ['DJANGO_SETTINGS_MODULE'] = "%s.settings" % project_name
from django.db import models
def textform_for_model(model_name):
app,mdl = model_name.split('.')
model = models.get_model(app,mdl)
opts = model._meta
field_list = []
for f in opts.fields + opts.many_to_many:
if not f.editable:
continue
formfield = f.formfield()
if formfield:
kw=[]
for a in ['queryset','maxlength','label','initial','help_text','required']:
if hasattr(formfield,a):
attr = getattr(formfield,a)
if attr in [True,False,None]:
kw.append("%s=%s" % (a,attr))
elif a == 'queryset':
kw.append("%s=%s" %(a,"%s.objects.all()" % attr.model.__name__))
elif attr:
kw.append("%s='%s'" % (a,attr))
f_text = " %s = forms.%s(%s)" % (f.name,formfield.__class__.__name__ ,','.join(kw))
field_list.append(f_text)
return "class %sForm(forms.Form):\n" % model.__name__ + '\n'.join(field_list)
if __name__ == "__main__":
cmdl = sys.argv
for n in cmdl[1:]:
print textform_for_model(n)
print "\n"
