Satchmo模板form.username未弹出

Question

注册/login.html已编辑

{% load i18n %}
    <div id="Login">
{% if form.non_field_errors %}
    <p class="error">
        {% for err in form.non_field_errors %}{{ err }}
            {% if not forloop.last %}<br/>{% endif %}
        {% endfor %}
    </p>
{% endif %}

<form method="post" action=".">{% csrf_token %}
<table>
    <tr><td><label for="id_username">{% trans 'USERNAME' %}:</label></td><td>{{ form.username }}</td></tr>
    {% if form.username.errors %}<tr><td class="error" colspan="2">***{{     form.username.errors|join:", " }}</td></tr>{% endif %}
    <tr><td><label for="id_password">{% trans 'PASSWORD' %}:</label></td><td>{{ form.password }}</td></tr>
    {% if form.password.errors %}<tr><td class="error" colspan="2">***{{     form.password.errors|join:", " }}</td></tr>{% endif %}
</table>

<input type="submit" value="{% trans 'sign in' %}" />
{% url registration_register as registration_register %}
{% if registration_register %}
    <span><a href="{% url registration_register %}">{% trans "register" %}</a></span>
{% endif %}
<input type="hidden" name="next"
{% if next %}
    value={{ next }} />
{% else %}
     {% url satchmo_account_info as accounturl %}
     {% if accounturl %} value="{% url satchmo_account_info %}" /> {% endif %}
{% endif %}
</form>

{% comment %} We jump through hoops with the urls so it doesn't bomb with django's built in unit tests.{% endcomment %}
{% url auth_password_reset as auth_password_reset %}
{% if auth_password_reset %}
    <p>{% trans "If you do not remember your password, please" %} 
        <a href="{% url auth_password_reset %}">{% trans "click here</a> to have it reset." %}</p>
{% endif %}
</div>

为什么不显示form.username和form.password输入框？我必须删除块标记{% extends shop/base.html %}。这会导致输入字段消失吗？

我所做的是删除{% block content %}{% endblock %}，并在base.html模板中使用{% include“注册/login.html”%}。我希望登录部分显示在左上角，而不是必须为位于{% block content %}中的登录字段单击" login“。

注册/login.html原始文件

{% extends "shop/base.html" %}
{% load i18n %}

{% block navbar %}
   <li class="first"><a href="{{ shop_base }}/">{% trans "Home" %}</a></li>
{% endblock %}

{% block content %}

{% if form.non_field_errors %}
<p class="error">{% for err in form.non_field_errors %}{{ err }}{% if not forloop.last %}<br/>{% endif %}
{% endfor %}</p>
{% endif %}

<form method="post" action=".">{% csrf_token %}

<tr><td><label for="id_password">{% trans 'Password' %}:</label></td><td>{{ form.password }}</td></tr>

        </div>

我尝试了一个{% include "registration/copy_login.html" %}，对内容做了一些改动。我还使用了<form action="{% url auth_login %}。当我在填写了登录/通行证后单击submit时，它会将我带到/accounts/login/，在这里我必须再次输入登录数据。

这是我的copy_login.html

 # copy_login.html
 ...
 <tr><td><label for="id_username">{% trans "Username" %}</label></td><td><input type="text" name="id_username" id="id_username" /></td></tr>
 <tr><td><label for="id_password">{% trans "Password" %}</label></td><td><input type="text" name="id_password" id="id_password" /></td></tr>
 ...

Answer 1

如果你的模板扩展了另一个模板，那么只有它在{% block %}...{% endblock %}中的代码才会“显示”。

假设我有这个base.html模板：

<html>
    <body>
        {% block body %}
        {% endblock %}
    </body>
</html>

然后，在这样的login.html模板中：

{% extends 'base.html' %}

this won't show up because it's not in a block

{% block body %}
    this will "show up"
{% endblock %}

仅针对用户代码的回答

第一个问题是，您可能试图将修改后的缩短注册/login.html包含到主模板中，但您将其隐藏在注释中：

<!-- I REMOVE REPLACED THE LINK BELOW WITH {% include "registration/login.html" %} -->

取消注释以查看结果。

原始模板注册/login.html由视图accounts.views.emaillogin和URL /accounts/login/使用，如果您转到任何需要登录的页面，URL URL都会重定向。你打破了它，但在这种情况下，你想在页面的中心显示一个更大的表单，而不仅仅是角落的小表单。您也不希望在页面上显示与其他表单相关的错误。难到不是么？不要破坏原始模板的用途。

一般答案

我建议首先将登录模板registration/login.html的重要部分复制粘贴到您包含在某个位置的较小模板中。这样你就不会在小模板中包含错误消息等，只包含最小的错误消息。如果登录失败，将显示通常的带有消息的大登录页面。您需要将action="."更改为

<form method="post" action="{% url auth_login %}?next={{ request.path }}">

注意:名称auth_login在satchmo_store/accounts/urls.py中定义为：

(r'^login/$', 'emaillogin', {'template_name': 'registration/login.html'}, 'auth_login'),

最后，你可以让它变干(不要重复)，但这对你来说不值得，因为模板会有很大的不同。
