Question

我使用了库django-filter，默认情况下它支持自己的过滤器表单。我在模板中使用{{filter.form}}来打印出来。有没有办法根据自己的需要配置和自定义它，这样我就不会使用“Φίλτρο”这个词而是其他的东西？

Answer 1

可以使用help_text属性为您的模型属性配置此单词（英文为Filter）。我建议只发布enligsh翻译是stackoverflow，以便非希腊人能够回答。

作为替代方案，您可以使用FILTERS_HELP_TEXT_FILTER=False设置（http://django-filter.readthedocs.org/en/latest/ref/settings.html）完全禁用此文本（过滤器）。

我也面临这个问题，我的解决方案如下：

<强> filters.py：

from django import forms
from django.utils.translation import ugettext as _
from django.forms.utils import flatatt
from django.contrib.auth.models import User
from .models import Zone, Location, Note, Price, Item, Unit, Category
import django_filters

class PriceFilter(django_filters.FilterSet):
    STATUS_CHOICES = (
        (0, _('Pending')),
        (1, _('Approved')),
        (2, _('Deleted')),
    )

    location = django_filters.ModelChoiceFilter(queryset=Location.objects.all(), widget=forms.Select(attrs={'class': 'form-control form-control-sm'}))
    item = django_filters.ModelChoiceFilter(queryset=Item.objects.all(), widget=forms.Select(attrs={'class': 'form-control form-control-sm'}))
    user = django_filters.ModelChoiceFilter(queryset=User.objects.all(), widget=forms.Select(attrs={'class': 'form-control form-control-sm'}))
    status = django_filters.ChoiceFilter(choices=STATUS_CHOICES, widget=forms.Select(attrs={'class': 'form-control form-control-sm'}))
    date = django_filters.DateFromToRangeFilter(widget=django_filters.widgets.RangeWidget(attrs={'class': 'datepicker form-control form-control-sm', 'placeholder': 'YYYY-MM-DD'}))
    class Meta:
        model = Price
        fields = ('location', 'item', 'unit', 'date', 'status', 'user', 'approved', )

<强> views.py：

from django.shortcuts import get_object_or_404, render, redirect
from django.urls import reverse
from django.contrib.auth.mixins import LoginRequiredMixin, PermissionRequiredMixin
from django.views import generic, View
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
from django.db.models import Count
from .models import Zone, Location, Note, Price, Item, Unit, Category
from .forms import NoteForm
from .filters import PriceFilter
...
class IndexView(generic.ListView):
    template_name = 'price/index.html'

    def get(self, request):
        price_list = Price.objects.all().order_by('-date').annotate(num_notes=Count('note'))
        price_filter = PriceFilter(request.GET, queryset=price_list)
        paginator = Paginator(price_filter.qs, 30)
        page = request.GET.get('page')
        try:
            prices = paginator.page(page)
        except PageNotAnInteger:
            prices = paginator.page(1)
        except EmptyPage:
            prices = paginator.page(paginator.num_pages)

        index = paginator.page_range.index(prices.number)
        max_index = len(paginator.page_range)
        start_index = index - 5 if index >= 5 else 0
        end_index = index + 5 if index <= max_index - 5 else max_index
        page_range = paginator.page_range[start_index:end_index]

        return render(request, self.template_name, {
            'prices': prices,
            'filter': price_filter.form,
            'page_range': page_range,
        })

<强>的index.html：

{% extends "base/base.html" %}
{% load i18n %}
{% load mptt_tags %}
{% block content %}

<div class="card border-light mb-3">
  <div class="card-header">{% trans 'Filter' %}</div>
  <div class="card-body">
    <form method="get">
    <div class="form-row">
      <div class="form-group col-md-2">
        <label for="inputEmail4" class="col-form-label">{% trans 'Item' %}</label>
        {{ filter.item }}
      </div>
      <div class="form-group col-md-2">
        <label for="inputEmail4" class="col-form-label">{% trans 'Location' %}</label>
        {{ filter.location }}
      </div>
      <div class="form-group col-md-2">
        <label for="inputEmail4" class="col-form-label">{% trans 'Author' %}</label>
        {{ filter.user }}
      </div>
      <div class="form-group col-md-3">
        <label for="inputEmail4" class="col-form-label">{% trans 'Date' %}</label>
        <div class="input-group mb-3 mb-sm-0">
        {{ filter.date }}
        </div>
      </div>
      <div class="form-group col-md-2">
        <label for="inputEmail4" class="col-form-label">{% trans 'Status' %}</label>
        {{ filter.status }}
      </div>
      <div class="form-group col-md-1">
        <label for="inputEmail4" class="col-form-label">{% trans 'Actions' %}</label>
        <button type="submit" class="btn btn-sm btn-primary">{% trans 'Filter' %}</button>
      </div>
    </div>
    </form>
  </div>
</div>

你可以像Django的形式一样使用过滤器，但它也有一些特定的小部件。我建议你查看文件： https://django-filter.readthedocs.io/en/develop/ref/filters.html#widget
