Django模板:如何在模板中使用模型中的字段?

时间:2021-07-05 02:46:33

In this template,

在这个模板,

<body><p>You searched for: <strong>{{ first }} {{ last }}</strong></p>

{% if lawyers %}
    <p>There are {{ lawyers|length }} schoolmates of <strong>{{ first }} {{ last }}</strong> in the database:</p>
    <ul>
        {% for lawyer in lawyers %}
        <li> {{ lawyer.first }} {{ lawyer.last }} {{ lawyer.firm_name }} {{ lawyer.school }} {{ lawyer.year_graduated }}</li>
        {% endfor %}
    </ul>

{% else %}
    <p><strong>{{ first }} {{ last }}</strong> has no classmates in the database. Try another lawyer.</p>
{% endif %} 

I pick up {{ first }} and {{ last }} from the search form but not the other parameters such as year_graduated.

我从搜索表单中获取{first}和{last},但不从其他参数(如year_graduation)中获取。

But I want to be able to say:

但是我想说

<p>You searched for: <strong> {{ first }} {{ last }}, class of {{ year_graduated }} </strong> </p>

How can I use lawyer.year_graduated in the template even though it is not in the search form?

我如何使用律师。year_graduated在模板中,即使它不在搜索表单中?

See my previous question for the view function.

请参阅我前面关于视图函数的问题。

Thank you.

谢谢你!

Well, the easy way would just be to add year_graduated to the context dict.

好的,简单的方法是将year_graduation添加到context dict语句中。

return render_to_response('search_results.html', {'lawyers': lawyers1, 'last': last_name, 'first': first_name, 'year_graduated': q_year[0], 'form': form})

The whole view could use some work to make things a little easier on yourself. Here are a few quick changes (including the ones discussed in the other question):

整个视图可以使用一些工作使事情变得更容易一些。这里有一些快速的变化(包括在另一个问题中讨论的):

def search_form(request):
    if request.method == 'POST':
        search_form = SearchForm(request.POST)
        if search_form.is_valid():
            last_name = search_form.cleaned_data['last_name']
            first_name = search_form.cleaned_data['first_name']
            fields = {}
            if last_name:
                lawyers = fields['last__iexact'] = last_name
            if first_name:
                lawyers = fields['first__icontains'] = first_name
            try:
                searched_lawyer = Lawyer.objects.get(**fields)
            except Lawyer.DoesNotExist:
                form = SearchForm()
                return render_to_response('not_in_database.html', {'last': last_name, 'first': first_name, 'form': form})
            except Lawyer.MultipleObjectsReturned:
                form = SearchForm(initial={'last_name': last_name})
                # Note: this breaks the current multiple returns functionality, up to you...
                return render_to_response('more_than_1_match.html', {'last': last_name, 'first': first_name, 'form': form}) 
            q_school = searched_lawyer.school
            q_year = searched_lawyer.year_graduated
            classmates = Lawyer.objects.filter(school__iexact=q_school).filter(year_graduated__icontains=q_year).exclude(last__icontains=last_name)
            form = SearchForm()
            return render_to_response('search_results.html', {'classmates': classmates, 'searched_lawyer': searched_lawyer, 'form': form})
    else:
        form = SearchForm()
        return render_to_response('search_form.html', {'form': form, })

So now rather than using "first" and "last" in your template, you'd be using "searched_lawyer.first", etc.. (But this means you would have access to all the attributes of that lawyer in your template)

因此,现在您应该使用“searched_lawyer”而不是在模板中使用“first”和“last”。第一”等。(但这意味着您可以访问模板中律师的所有属性)
