Question

我正在尝试立即渲染表单和表单集。 formset工作正常（我认为），但表单没有验证（好像没有发布数据）

我试过玩按钮，但它的主要提交功能来自js。

这些表单都是独立工作的，但是在提交给thegetehr时却没有，所以看起来问题出现在视图中这是代码：

views.py

from django.shortcuts import render, render_to_response
from django.http import HttpResponseRedirect
from forms import LessonForm, AddMaterialForm
from models import Lesson, SUBJECT_OPTIONS, Materials, MATERIAL_TYPES
from django.forms.formsets import formset_factory

def Create_Lesson(request):
    AddMaterials=formset_factory(AddMaterialForm, extra=9)
    if request.method == "POST": # If the form has been submitted...
        lesson = LessonForm(request.POST, prefix="lesson") # A form bound to the POST data
        formset = AddMaterials(request.POST, request.FILES) # A form bound to the POST data
        if lesson.is_valid() and formset.is_valid(): # All validation rules pass
            lesson = lesson.save(commit=False)
            lesson.creator = request.user
            lesson.save()
            for form in formset:
                form = form.save(commit=False)
                form.lesson = lesson.pk
                form.save()
            return render(request, 'index.html',)
    else:
        lesson= LessonForm(prefix='lesson') # An unbound form
        formset = AddMaterials()
    return render(request, 'create_lesson/create.html', {
    'form': lesson,'formset':formset
})

html的

    <form id="create_lesson_form" method="post" action="">
    <h2>1: Create Your Lesson</h2>

        {{ form.non_field_errors }}
        <label for="subject"><span>Subject</span></label>
        {{form.subject}}
        {{ form.subject.errors }}
        <label for="title"><span>Title</span></label>
        <input type="text" id="title" name="name" placeholder="Give it a name"/>
        {{ form.name.errors }}
        <label class="error" for="title" id="title_error">You must choose a title!</label>            
        <label for="subtitle"><span>Subtitle</span></label>
        <input type="text" id="subtitle" name="subtitle" placeholder="Type your subtitle here"/>
        {{ form.subtitle.errors }}
        <label class="error" for="subtitle" id="subtitle_error">are you sure you want to leave subtititle blank?</label>
        <label for="description"><span>Description</span></label>
        <textarea id="description" name= "description" cols="42" rows="5" placeholder="why is it important? this can be a longer description"'></textarea>
        {{ form.description.errors }}
        <label class="error" for="description" id="description_error">are you sure you want to leave the description blank?</label>
        <label for="success" id="Goals_title"><span>Goals</span></label>
        <textarea id="success" name="success" cols="42" rows="5" placeholder="explain what sucess might look like for someone doing this lesson...what does mastery look like?" '></textarea>
        {{ form.success.errors }}
        <label class="error" for="success" id="success_error">are you sure you want to leave the goals blank?</label>
    {{ form.directions.errors }}
        <label class="error" for="directions" id="directions_error">are you sure you do not want to include dierections?</label>
    <label for="directions" id="Directions_title"><span>Directions</span></label>
        <textarea id="directions" name="directions" cols="42" rows="5" placeholder="you can add simple directions here" '></textarea><br>
    </form>


    <form id="add_elements_form" method="post" action="">
    {% csrf_token %}
    {{ formset.as_p}}
    <button type='submit' id='finish'>Finish Editing Lesson</button>
    </form>

Answer 1

这将同时提交表单和formset。

//When your uploading files or images don't forget to put "multipart/form-data" 
//   in your form. 
//To connect formset in your form, don't forget to put the model in the formset 
//   for instance.
//In this you can add many lines as you want or delete it.

<强> forms.py

class LessonForm(forms.ModelForm):
    class Meta:
        model = Lesson


MaterialsFormset = inlineformset_factory(Lesson, Materials, 
    fields=('field_name', 'field_name'), can_delete=True)

<强> views.py

def view_name(request):
    form = LessonForm()
    formset = MaterialsFormset(instance=Lesson())
    if request.method == 'POST':
        form = LessonForm(request.POST)
        if form.is_valid():
            lesson = form.save()
            formset = MaterialsFormset(request.POST, request.FILES,
                instance=lesson)
            if formset.is_valid():
                formset.save()
                return render(request, 'index.html',)
    return render(request, "page.html", {
        'form': form, 'formset': formset
    })

html

<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    {{ formset.as_p }}
    <input type="submit" value="Save"/>
</form>

Answer 2

您只需要一个表单标记。如果您希望同时接收所有数据，则需要使用一个表单标记包装所有字段。
