【问题描述】:
我有一个关于 Django 中的 ModelForms 的问题。如果我使用 ModelForms 从模型创建表单,那么表单字段将如何链接到这些 M2M 关系?我的意思是如果我有:
模型.py
class Recipe(models.Model):
title = models.CharField(max_length=100)
category = models.ForeignKey(Category)
cuisineType = models.ForeignKey(CuisineType)
description = models.TextField()
serving = models.CharField(max_length=100)
cooking_time = models.TimeField()
ingredients = models.ManyToManyField(RecipeIngredient)
directions = models.TextField()
image = models.OneToOneField(Image)
added_at = models.DateTimeField(auto_now_add=True)
last_update = models.DateTimeField(auto_now=True)
added_by = models.ForeignKey(UserProfile, null=False)
tags = models.ManyToManyField(Tag,blank=True)
class Category(models.Model):
category = models.CharField(max_length=100)
category_english = models.CharField(max_length=100)
#slug = models.SlugField(prepopulate_from=('name_english',))
slug = models.SlugField()
parent = models.ForeignKey('self', blank=True, null=True, related_name='child')
description = models.TextField(blank=True,help_text="Optional")
class Meta:
verbose_name_plural = 'Categories'
#sort = ['category']
Forms.py
class RecipeForm(ModelForm):
class Meta:
model = Recipe
exclude = ('added_at','last_update','added_by')
Views.py
def RecipeEditor(request, id=None):
form = RecipeForm(request.POST or None,
instance=id and Recipe.objects.get(id=id))
# Save new/edited Recipe
if request.method == 'POST' and form.is_valid():
form.save()
return HttpResponseRedirect('/recipes/') #TODO: write a url + add it to urls .. this is temp
return render_to_response('adding_recipe_form.html',{'form':form})
那么我应该像我一样为彼此相关的 2 个模型创建 1 个模型表单吗?还是每个模型的模型形式?如果我这样做,我将如何从另一个模型中排除字段?我有点困惑。
