Question

我对Django表单有一个奇怪的问题。有这个表单，我可以根据单击提交按钮完成不同的操作。在开发的某个阶段，一切都运行良好：我的表单验证正常，它正在做我想要的。但是现在（我真的不知道我可以做错什么来打破它），提交动作就行不通了。我没有收到任何错误，它什么也没做。

以下是我的forms.py文件中的代码：

class AssetModif(forms.Form):    
    def __init__(self, *args, **kwargs):
        proj_id = kwargs.pop('proj_id')
        super(AssetModif, self).__init__(*args, **kwargs)
        self.proj_id = proj_id
        EPISODE_CHOICES = [('-1', '------------')]
        for e in Project.objects.filter(proj_id_parent=proj_id).order_by('proj_saison', 'proj_numepisode'):
            EPISODE_CHOICES.append((e.proj_name,
                "e" + str(e.proj_saison).zfill(2) + str(e.proj_numepisode).zfill(2) +
                "_" + e.proj_name))
            self.fields['episodes'].choices = EPISODE_CHOICES
            self.fields['episode_etat'].choices = EPISODE_CHOICES

    TYPE_CHOICES = [(type.type_name, type.type_name) for type in Type.objects.all()]
    ASSET_CHOICES = (('', '-- choisir un type en premier'))

    type = forms.ChoiceField(choices=TYPE_CHOICES,
                widget=forms.Select(attrs={'onchange':'get_asset_from_type();'}))
    asset = LazyChoiceField(choices=ASSET_CHOICES, required=False)
    episodes = forms.ChoiceField()

    etat = forms.CharField()
    episode_etat = forms.ChoiceField()

    commentaire = forms.CharField(widget=forms.Textarea)

还有一些save_action（）方法，如果有人问我可以添加。我的views.py中的代码：

def modif_asset(request):
    try:
        proj = request.session['proj']
        nom = request.session['nom']
    except:
        request.session['proj'] = 1
        proj = request.session['proj']
        request.session['nom'] = ""
        nom = ""

    if request.method == 'POST' and (request.POST.get("action_add_episode", "") == "Ajout Episode"):
        form = AssetModif(request.POST, proj_id = request.session['proj'])
        if form.is_valid():
            asset = form.save_episode()
            #return HttpResponseRedirect(reverse('menu'))
            return render_to_response("asset/modif.html", {'proj':proj, 'form':form, 'asset':asset}, context_instance=RequestContext(request))
        else:
            asset = form.save_episode()
            return render_to_response("asset/modif.html", {'proj':proj, 'form':form, 'asset':"toooooooo"}, context_instance=RequestContext(request))

    elif request.method == 'POST' and (request.POST.get("action_delete_asset", "") == "Suppression BDD"):
        form = AssetModif(request.POST, proj_id = request.session['proj'])
        if form.is_valid():
            asset = form.delete_asset()
            #return HttpResponseRedirect(reverse('menu'))
            return render_to_response("asset/modif.html", {'proj':proj, 'form':form, 'asset':asset}, context_instance=RequestContext(request))

    elif request.method == 'POST' and (request.POST.get("action_ajout_etat", "") == "Ajout Etat"):
        form = AssetModif(request.POST, proj_id = request.session['proj'])
        if form.is_valid():
            asset = form.save_etat()
            return render_to_response("asset/modif.html", {'proj':proj, 'form':form, 'asset':asset}, context_instance=RequestContext(request))

    elif request.method == 'POST' and (request.POST.get("action_ajout_comment", "") == "Ajout Commentaire"):
        form = AssetModif(request.POST, proj_id = request.session['proj'])
        if form.is_valid():
            asset = form.save_comment()
            return render_to_response("asset/modif.html", {'proj':proj, 'form':form, 'asset':asset}, context_instance=RequestContext(request))

    else:
        form = AssetModif(proj_id=request.session['proj'])

    c = {'proj': proj, 'form':form, 'asset':" Miiii "}
    c.update(csrf(request))
    return render_to_response("asset/modif.html", c, context_instance=RequestContext(request))

我的模板是这样的：

<form method="POST" action="" name="form_modif">{% csrf_token %}
  <table>
    <tr><td> Type </td><td> {{ form.type }} </td>
    <td> Asset </td><td> {{ form.asset }} </td></tr>
  </table>

  <div id="ajout_episode">
    <p><b> Premier &eacute;pisode de l'asset </b></p>
    <table>
      <tr><td>Episode</td><td> {{ form.episodes }}</td></tr>
      <tr><td><input type="submit" name="action_add_episode" value="Ajout Episode" /></td></tr>
    </table>
  </div>

  <div id="creation_etat">
    <p><b> Ajout d'un &eacute;tat </b></p>
    <table>
      <tr><td>Etat</td><td> {{ form.etat }}</td></tr>
      <tr><td>Premier &eacute;pisode de l'&eacute;tat</td><td> {{ form.episode_etat }}</td></tr>
      <tr><td><input type="submit" name="action_ajout_etat" value="Ajout Etat" /></td></tr>
    </table>
  </div>

  <div id="ajout_comment">
    <p><b> Ajout d'un commentaire </b></p>
    <table>
      <tr><td> {{ form.commentaire }}</td></tr>
      <tr><td> <input type="submit" name="action_ajout_comment" value="Ajout Commentaire" /></td></tr>
    </table>
  </div>

  <div id="suppression_bdd">
    <p><b> Suppression de l'asset en BDD </b></p>
    <input type="submit" onclick="return verifier();" name="action_delete_asset" value="Suppression BDD" />
</form>

我非常感谢任何帮助，因为我完全坚持了它

Answer 1

不是一个答案太多，而是关于获取错误的指示。

您的第一个起点应该是查找字段错误，您目前根本没有输出它们。

所以，如果你这样做

    <div id="ajout_episode">
    <p><b> Premier &eacute;pisode de l'asset </b></p>
    <table>
    <tr><td>Episode</td><td> {{ form.episodes }}</td></tr>

    <tr><td><input type="submit" name="action_add_episode" value="Ajout Episode" /></td></tr>
    </table>
    {{form.episodes.errors}}
    </div>

然后它将显示该字段的错误。您可以使用以下代码段来检查错误：http://djangosnippets.org/snippets/1094/

表单也有一个全局错误变量，但我目前无法找到或记住它的名称。

Answer 2

<form method="POST" action="url_to_your_view" name="form_modif">

表格未在Django中验证
