create form from 2 models python django: [Errno 2] No such file or directory -
i trying create form 2 models using python , django. below shows models:
# create models here. class action(models.model): name = models.charfield("action name", max_length=50) keywords = models.charfield("keywords", max_length=50) object = models.charfield("object", max_length=50, blank=true, null=true) uploaddate = models.datefield("date", default=get_current_date) uploadedby = models.charfield("uploadedby", max_length=50, default="") class image(models.model): image = models.filefield(upload_to=get_upload_file_name, default="") action = models.foreignkey(action) and form classes:
class actionform(modelform): #bind form action model class meta: model = action fields = ['name','keywords', 'object', 'uploadedby', 'uploaddate'] class imageform(modelform): class meta: model= image fields =['image'] the code in views creates page createform.html template:
def actioncreate(request): if request.method == "get": #create object - actionform form = actionform; form2 = imageform; #pass return render(request,'app/createform.html', { 'form':form, 'form2':form2}) elif request.method == "post": # take of user data entered create new action instance in table form = actionform(request.post, request.files) form2 = imageform(request.post, request.files) if form.is_valid() , form2.is_valid(): #prepare action model act = form.save(commit=false) #set action_id foreignkey act.action_id = form2.save() act.save() return httpresponseredirect('/actions') else: form = actionform() form2 = imageform; return render(request,'app/createform.html', { 'form':form, 'form2':form2 }) form template:
<form method="post" enctype="multipart/form-data"> {% csrf_token %} <ul> {{ form.as_ul }} {{ form2.as_ul }} </ul> <button type="submit">save</button> <button name="cancel" onclick="navigate({% url 'home' %})">cancel</button> </form> the form displays fine when page accessed, once submitted error:
[errno 2] no such file or directory
and doesnt seem line:
act.action_id = form2.save() the models created definiely has of fields referring , although getting error first half (actionform) saves database, not imageform. appreciated!

you need specify sub-directory of media_root upload exists on local file system. check being returned get_upload_file_name function , check that sub-directory of media_root (defined in settings.py) on local file system:
class image(models.model): image = models.filefield(upload_to=get_upload_file_name, default="") see here:
https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.filefield.upload_to
