django-filter更改默认表单外观

Question

我已经使用了库django-filter，它默认支持自己的过滤器表单。我使用模板中的{{filter.form}}将其打印出来。有没有一种方法可以根据我自己的需要进行配置和自定义，这样我就不会采用“Φ”这个词，而是其他的东西？

Answer 1

此字（这是英语滤波器）可以通过将模型的属性使用help_text属性进行配置。我建议只发布enligsh翻译是stackoverflow，以便非希腊人民将能够回答。

也可以使用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）。

Answer 2

我面对这个问题也，我的解决办法如下：

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',) 

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, 
     }) 

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的窗体一样使用过滤器，但它也有一些特定的小部件。我建议你检查文件： https://django-filter.readthedocs.io/en/develop/ref/filters.html#widget
