Python - Django - 使用 Bootstrap 样式修改注册页

reg2 函数：

from django.shortcuts import render, HttpResponse

from app01 import models

def reg2(request):

    form_obj = RegForm()  # GET 请求

    if request.method == "POST":

        form_obj = RegForm(request.POST)

        if form_obj.is_valid():

            pass

    return render(request, "reg2.html", {"form_obj": form_obj})

在 bootstrap 上找到表单样式，https://v3.bootcss.com/css/#forms

label 标签处用的是 form-group 样式

reg2.html：

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>注册页面</title>

    <link rel="stylesheet" href="/static/bootstrap/css/bootstrap.min.css">

</head>

<body>

<div class="container">

    <form action="/reg2/" method="post" novalidate>

        {% csrf_token %}

        <div class="form-group">

            {{ form_obj.username.label }}

            {{ form_obj.username }}

            <span>{{ form_obj.username.errors.0 }}</span>

        </div>

        <div class="form-group">

            {{ form_obj.password.label }}

            {{ form_obj.password }}

            <span>{{ form_obj.password.errors.0 }}</span>

        </div>

        <p><input type="submit"></p>

    </form>

</div>

</body>

</html>

input 标签处用的是 form-control 样式

在 views.py 的 form 类中用 widgets 进行添加该样式

from django import forms

from django.forms import widgets

class RegForm(forms.Form):

    username = forms.CharField(

        min_length=5,

        label="用户名",

        error_messages={

            "min_length": "用户名不能少于5位！",

        },

        widget=widgets.TextInput(attrs={"class": "form-control"})

    )

    password = forms.CharField(

        min_length=6,

        label="密码",

        error_messages={

            "min_length": "密码不能少于6位！",

        },

        widget=widgets.PasswordInput(attrs={"class": "form-control"}, render_value=True)

    )

button 处用的是 btn btn-default 样式

直接在 index.html 处添加就好了

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>注册页面</title>

    <link rel="stylesheet" href="/static/bootstrap/css/bootstrap.min.css">

</head>

<body>

<div class="container">

    <form action="/reg2/" method="post" novalidate>

        {% csrf_token %}

        <div class="form-group">

            {{ form_obj.username.label }}

            {{ form_obj.username }}

            <span>{{ form_obj.username.errors.0 }}</span>

        </div>

        <div class="form-group">

            {{ form_obj.password.label }}

            {{ form_obj.password }}

            <span>{{ form_obj.password.errors.0 }}</span>

        </div>

        <p><input type="submit" class="btn btn-default"></p>

    </form>

</div>

</body>

</html>

运行结果：

input 处太长了，把它布局到中间

index.html：

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>注册页面</title>

    <link rel="stylesheet" href="/static/bootstrap/css/bootstrap.min.css">

</head>

<body>

<div class="container">

    <div class="row">

        <div class="col-md-6 col-md-offset-3">

            <form action="/reg2/" method="post" novalidate>

                {% csrf_token %}

                <div class="form-group">

                    {{ form_obj.username.label }}

                    {{ form_obj.username }}

                    <span>{{ form_obj.username.errors.0 }}</span>

                </div>

                <div class="form-group">

                    {{ form_obj.password.label }}

                    {{ form_obj.password }}

                    <span>{{ form_obj.password.errors.0 }}</span>

                </div>

                <p><input type="submit" class="btn btn-default"></p>

            </form>

        </div>

    </div>

</div>

</body>

</html>

左边空 3 份，中间占 6 份，右边剩下 3 份

运行结果：

输入内容，点击 “提交”

错误提示可以使用 help-block 样式

reg2.html：

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>注册页面</title>

    <link rel="stylesheet" href="/static/bootstrap/css/bootstrap.min.css">

</head>

<body>

<div class="container">

    <div class="row">

        <div class="col-md-6 col-md-offset-3">

            <form action="/reg2/" method="post" novalidate>

                {% csrf_token %}

                <div class="form-group {% if form_obj.username.errors.0 %}has-error{% endif %}">

                    {{ form_obj.username.label }}

                    {{ form_obj.username }}

                    <span class="help-block">{{ form_obj.username.errors.0 }}</span>

                </div>

                <div class="form-group {% if form_obj.password.errors.0 %}has-error{% endif %}">

                    {{ form_obj.password.label }}

                    {{ form_obj.password }}

                    <span class="help-block">{{ form_obj.password.errors.0 }}</span>

                </div>

                <p><input type="submit" class="btn btn-default"></p>

            </form>

        </div>

    </div>

</div>

</body>

</html>
