我正在尝试同时使用 django 消息和引导程序。

我也检查了这个问题；

django 消息未显示

但是，我已经应用了那里写的内容。

我的设置.py;

from django.contrib.messages import constants as messages

# some other codes #

MESSAGE_TAGS = {
messages.DEBUG: 'alert-info',
messages.INFO: 'alert-info',
messages.SUCCESS: 'alert-success',
messages.WARNING: 'alert-warning',
messages.ERROR: 'alert-danger',
}

# some other codes #

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
.
.
# other apps
]

# some other codes #

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.locale.LocaleMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'django_pdb.middleware.PdbMiddleware',
]

# some other codes #

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, 'templates')],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',

            'django.contrib.messages.context_processors.messages',
        ],
    },
},
]

我的产品/views.py；

# some other imports #

from django.contrib import messages

def oxford(request):
    search_result = {}
    if 'word' in request.GET:
        form = DictionaryForm(request.GET)
        if form.is_valid():
            search_result = form.search()
            messages.success(request, 'Your query is successful!')
    else:
        form = DictionaryForm()
        messages.warning(request, 'Please correct the error.')
    return render(request, 'products/oxford.html', {'form': form, 'search_result': search_result})

我的产品/urls.py；

# some imports here #

    # some other urls here #

      {{ message }}
    </div>
  {% endfor %}
{% endif %}

我在这里找不到我缺少的东西。感谢您的时间和回答。

如果表单对 try 无效，请添加其他消息：

# some other imports #

from django.contrib import messages

    # some other codes # 

def oxford(request):
    search_result = {}
    if 'word' in request.GET:
        form = DictionaryForm(request.GET)
        if form.is_valid():
            search_result = form.search()
            messages.success(request, 'Your query is successful!')
        else:
            messages.warning(request, 'form is not valid.')
    else:
        form = DictionaryForm()
        messages.warning(request, 'Please correct the error.')
    return render(request, 'products/oxford.html', {'form': form, 'search_result': search_result})
