我对Django中的ModelForms有疑问。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:在Django中使用ManyToMany关系的模型
Models.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})
那么我应该创建1周的ModelForm为与我相关的2款车型?或每个模型的模型?如果我做了一个,我将如何从另一个模型中排除字段?我有点困惑。
谢谢,这个回答我的问题。但是现在,我会有一个或多个视图功能吗?如果2,每个人都会直接进入同一页面? – Morano88
如果你只是添加,更新,删除条目而烦恼,那么我建议你看看[通用视图](https://docs.djangoproject.com/en/dev/ref/generic-views/?from=olddocs #创建更新,删除泛型视角)。如果您希望灵活性更好,请为每个模型创建视图和模板。 – Pannu
