Python Django表单字段未显示

你好，我的表格不能用了。按钮会显示，但字符字段不会显示。我尝试使用带有“sent”参数的if语句，结果成功了。我只是跟着django医生。我在其他帖子中没有找到解决方案

这是我的表格。py：

from django import forms

class CharacterForm(forms.Form):
    character_name = forms.CharField(label='Search', max_length=30)

from django.shortcuts import render
from .forms import CharacterForm

def index(request):
    return render(request, 'perso/pages/index.html')

def get_character(request):
        character_name = ''
        sent = False
        if request.method == 'POST':
            form = CharacterForm(request.POST)
            if form.is_valid():
                character_name = form.cleaned_data['character_name']
                sent = True
        else:
            form = CharacterForm()
        return render(request, 'perso/pages/index.html', {
            'form': form, 
            'character_name': character_name,
            'sent': sent
        })

from django.conf.urls import url 

from . import views

app_name = 'perso'
urlpatterns = [
    url(r'^$', views.index, name="index"),
]

<form action="{% url "perso:index" %}" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Submit" />
</form>

视图.py：

from django import forms

class CharacterForm(forms.Form):
    character_name = forms.CharField(label='Search', max_length=30)

from django.shortcuts import render
from .forms import CharacterForm

def index(request):
    return render(request, 'perso/pages/index.html')

def get_character(request):
        character_name = ''
        sent = False
        if request.method == 'POST':
            form = CharacterForm(request.POST)
            if form.is_valid():
                character_name = form.cleaned_data['character_name']
                sent = True
        else:
            form = CharacterForm()
        return render(request, 'perso/pages/index.html', {
            'form': form, 
            'character_name': character_name,
            'sent': sent
        })

from django.conf.urls import url 

from . import views

app_name = 'perso'
urlpatterns = [
    url(r'^$', views.index, name="index"),
]

<form action="{% url "perso:index" %}" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Submit" />
</form>

Perso是应用程序的名称，Perso中的url.py：

from django import forms

class CharacterForm(forms.Form):
    character_name = forms.CharField(label='Search', max_length=30)

from django.shortcuts import render
from .forms import CharacterForm

def index(request):
    return render(request, 'perso/pages/index.html')

def get_character(request):
        character_name = ''
        sent = False
        if request.method == 'POST':
            form = CharacterForm(request.POST)
            if form.is_valid():
                character_name = form.cleaned_data['character_name']
                sent = True
        else:
            form = CharacterForm()
        return render(request, 'perso/pages/index.html', {
            'form': form, 
            'character_name': character_name,
            'sent': sent
        })

from django.conf.urls import url 

from . import views

app_name = 'perso'
urlpatterns = [
    url(r'^$', views.index, name="index"),
]

<form action="{% url "perso:index" %}" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Submit" />
</form>

个人模板索引中的我的表单：

from django import forms

class CharacterForm(forms.Form):
    character_name = forms.CharField(label='Search', max_length=30)

from django.shortcuts import render
from .forms import CharacterForm

def index(request):
    return render(request, 'perso/pages/index.html')

def get_character(request):
        character_name = ''
        sent = False
        if request.method == 'POST':
            form = CharacterForm(request.POST)
            if form.is_valid():
                character_name = form.cleaned_data['character_name']
                sent = True
        else:
            form = CharacterForm()
        return render(request, 'perso/pages/index.html', {
            'form': form, 
            'character_name': character_name,
            'sent': sent
        })

from django.conf.urls import url 

from . import views

app_name = 'perso'
urlpatterns = [
    url(r'^$', views.index, name="index"),
]

<form action="{% url "perso:index" %}" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Submit" />
</form>

{%csrf_令牌%}
{{form.as_p}}

以下是浏览器中显示的内容：

<form action="/perso/" method="post">
    <input type='hidden' name='csrfmiddlewaretoken' value='IWmBEknyibHw4LpvjnyfLWKcUOXLbw27RdHgR7GjhTDelCLGZ51QeF3y9wRyC0Mg' />
    <input type="submit" value="Submit" />
</form>

查菲尔德号不见了。控制台中没有错误。

您的代码中有一些异常，您遗漏了呈现函数中的模板名称参数。在渲染函数中提供相应HTML文件的

模板名称

。您还没有提供字符名和sent变量的默认参数。见文件

您犯了一个错误，没有为views.py中正在模板中设置表单的函数创建

url.py

模式

from django.conf.urls import url 
from . import views

app_name = 'perso'
urlpatterns = [
    url(r'^$', views.index, name="index"),
    url(r'^character$', views.get_character, name="character"),
]

此外，您还需要在post请求的

URL

链接中的

模板中进行更正

<form action="{% url "perso:character" %}" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Submit" />
</form>


{%csrf_令牌%}
{{form.as_p}}

现在您的表单将在

现在，当您的视图收到
get
请求时，您的表单将在什么是
character\u name
上可用。您的代码中存在异常。当您的视图收到
get
请求时，请检查哪些是
character\u name
。您的代码中存在异常。看看，谢谢！我添加了默认变量和模板名称。查菲尔德号还没出来，给你！这看起来很傻，但我找不出来。@dcprod检查一下是的，你很傻，你没有任何指向发送formI的视图函数的url链接。我正在开始django，我不知道我们必须这样做。非常感谢@dcprod首先通过一些好的源代码。这会让你的想法更清晰，麻烦更少。谢谢！我添加了默认变量和模板名称。查菲尔德号还没出来，给你！这看起来很傻，但我找不出来。@dcprod检查一下是的，你很傻，你没有任何指向发送formI的视图函数的url链接。我正在开始django，我不知道我们必须这样做。非常感谢@dcprod首先通过一些好的源代码。它会让你的想法更清晰，麻烦更少。
