Question

我有一个页面，其中有一个/ tag / name_of_tag路径，您可以看到所有带有该标签标记的帖子。在页面内，您还可以选择表单中的另一个标签并转到该标签。问题在于，它转到/ tag /？search = searched_tag而不是转到/ tag / searched_tag 如何更改它不离开？search =部分？

urls.py：

url(r'tag/(?P<input_tag>\w+)$', views.tag_view, name='tag'),

views.py：

def tag_view(request, input_tag):
    form = TagSearchForm()
    if request.method == 'GET':
        form = TagSearchForm(request.GET)
        if form.is_valid():
            input = form.cleaned_data['search']
            print(input)
            return redirect('fortykwords:tag_view', input)

    else:
        form = SearchForm()    

    latest_post_list = Post.objects.filter(tags=input_tag, status__exact="published")
    paginator = Paginator(latest_post_list, 3)
    page = request.GET.get('page')
    posts = paginator.get_page(page)
    context = {'latest_post_list': latest_post_list, 'page_tag': input_tag, 'form': form}
    return render(request, 'fortykwords/tag.html', context)

forms.py：

class TagSearchForm(forms.Form):
    search = tagulous.forms.SingleTagField(
    tag_options=tagulous.models.TagOptions(
        autocomplete_view='fortykwords:post_tags_autocomplete'
    ),
    label='Tags',
    required=True,
    help_text=_('Filter by lead tags.  You can organize leads by any tag you want.'),
)

tag.html：

{% extends "base_generic.html" %}

{% block content %}

<form action="." method="get">
    {{ form }}
    <input type="submit" value="Submit" />
</form>

<h3>Posts with the tag {{ page_tag }}</h3>

{% if latest_post_list %}
    <ul>
        {% for post in latest_post_list %}
            <li> {{ post.author }} {{ post.pub_date }} 
                    <br>  
            <a href="{% url 'fortykwords:detail' post.id %}">{{ post.title }}</a></li>
            {% for tag in post.tags.all %}
                <a href="{% url 'fortykwords:tag' tag.name %}">{{ tag.name }}</a>
            {% endfor %}
        {% endfor %}
    </ul>
{% else %}
    <p>No posts are available.</p>
{% endif %}
{% endblock %}

Answer 1

您需要将input的参数redirect提供给input_tag=input。

示例：

return redirect('fortykwords:tag_view', input_tag=input)

Answer 2

它显示为/tag/?search=searched_tag，因为您的表单是由GET提交的，但从未进入重定向。似乎is_valid()返回了False。

我已经测试了您的代码的非常相似的版本，并且认为它不是tagulous的错误，但是仍然有兴趣知道出了什么问题（我写了tagulous）。发现了几个可以简化代码的地方，因此请尝试：:

def tag_view(request, input_tag):
    # Can't see any POSTs in your example, so you can pass the form GET here
    # Might also be nice to pass the original tag in so it shows in the form
    form = TagSearchForm(request.GET, initial={'search': input_tag})

    # The form already has the GET, so you can go straight into the is_valid
    if form.is_valid():
        input = form.cleaned_data['search']
        print('Valid: ', input)
        return redirect('fortykwords:tag_view', input)

    else:
        print('Invalid: ', form.errors, form.non_field_errors)
    # You can remove the else for if not GET, which would never be reached

    # on to pagination as before

（尽管我建议使用ipdb而不是print）

使用重定向将我发送到/ tag /？search = input而不是/ tag / input（来自表单的Django URL参数）
