那里。 我定义了一个名为LoginForm的类:
class LoginForm(FlaskForm):
email = StringField('Email', validators=[DataRequired(), Length(5, 64), Email()])
password = PasswordField('Password', validators=[DataRequired()])
remember_me = BooleanField('Remember me')
submit = SubmitField('Log In')
然后我在模板login.html
:
{% extends "base.html" %}
{% import "bootstrap/wtf.html" as wtf %}
{{ wtf.quick_form(form) }}
我认为这有点难看。所以,我以正常的方式渲染字段:
<form action="" method="POST" role="form" class="form">
{{ form.hidden_tag() }} {{ wtf.form_errors(form, hiddens="only") }}
<div class="form-group required">
<label class="control-label" for="email">Email</label>
{{ form.email(class="form-control",id="email",required="required",type="text",value="",placeholder="Enter email") }}
</div>
<div class="form-group required">
<label class="control-label" for="password">Password</label>
{{ form.password(class="form-control",id="password",required="required",type="password",value="",placeholder="Enter email") }}
</div>
<div class="checkbox">
<label>
<input id="remember_me" name="remember_me" type="checkbox" value="y"> Remember me
</label>
</div>
{{ form.submit(class="btn btn-success btn-block") }}
<a href="{{ url_for('auth.register') }}" class="btn btn-danger btn-block" role="button">Register</a>
</form>
现在它同意我的看法。但我遇到了一个问题:当我点击绿色登录按钮时,它不会验证数据(如电子邮件地址的格式)。我该如何解决这个问题?
答案 0 :(得分:1)
首先我认为它没有验证。感谢@BurhanKhalid提醒我。 它只是没有显示错误。我改变了代码并且它有效。
{% if form.email.errors %}
<div class="form-group required has-error">
{{ form.email(class="form-control",id="email",required='required',type="text",value="",placeholder="Enter email") }}
{% for error in form.email.errors %}
<p class="help-block">{{ error }}</p>
{% endfor %}
{% else %}
<div class="form-group required">
{{ form.email(class="form-control",id="email",required='required',type="text",value="",placeholder="Enter email") }}
{% endif %}
</div>
