My model currently has three related objects (there are more, but only three are relevant to this problem). User, Network, and Email. What I want to be able to do is have a defined set of Networks, and to allow each User to have an Email address on each Network (these are slightly more complex, but I've cut them down to what I think is relevant).
class User(UserMixin, db.Model):
"""
The User object.
"""
__tablename__ = 'users'
id = db.Column(db.Integer, primary_key=True)
# email = db.Column(db.String(64), unique=True, index=True)
username = db.Column(db.String(64), unique=True, index=True)
password_hash = db.Column(db.String(128))
firstname = db.Column(db.String(64))
lastname = db.Column(db.String(64), unique=False, index=True)
email = db.relationship('Email', backref='user')
class Network(db.Model):
__tablename__ = 'networks'
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(64), index=True)
emails = db.relationship('Email', backref='network', lazy='dynamic')
class Email(db.Model):
__tablename__ = 'emails'
id = db.Column(db.Integer, primary_key=True)
network_id = db.Column(db.Integer, db.ForeignKey('networks.id'))
user_id = db.Column(db.Integer, db.ForeignKey('users.id'))
address = db.Column(db.String(64))
My view:
@main.route('/edit-profile', methods=['GET', 'POST'])
@login_required
def edit_profile():
form = EditProfileForm(obj=current_user)
form.email.min_entries=Network.query.count()
if form.validate_on_submit():
form.populate_obj(current_user)
db.session.add(current_user)
db.session.commit()
flash("Your profile has been updated.")
return redirect(url_for('.user', username=current_user.username))
return render_template('edit_profile.html', form=form)
And forms:
class EmailForm(Form):
id = HiddenField('Id')
address = StringField('Address', validators=[DataRequired(), Email()])
network = QuerySelectField(query_factory=get_networks)
class EditProfileForm(Form):
username = StringField('Username', validators=[Length(0, 64),
Regexp('[A-Za-z0-9_\.\-]'),
DataRequired()])
firstname = StringField('First name', validators=[Length(0, 64),
DataRequired()])
lastname = StringField('Last name', validators=[Length(0, 64),
DataRequired()])
email = ModelFieldList(FormField(EmailForm), model=Email)
submit = SubmitField('Submit')
The outer form's HTML:
{% extends "base.html" %}
{% import "bootstrap/wtf.html" as wtf %}
{% block title %}Edit Profile{% endblock %}
{% block page_content %}
<div class="page-header">
<h1>Edit Your Profile</h1>
</div>
<div class="col-md-8">
{{ wtf.quick_form(form) }}
</div>
{% endblock %}
Here's what it looks like in both Chrome and Firefox:
So I'm obviously doing something wrong, since:
- The sub-form's widgets look nothing like those of the outer form, and
- The sub-form keeps being shown over the top of the outer form.
Where have I gone wrong with this? I tried not using wtf.quick_form() but couldn't get it to look right manually, either. To do that, I replaced the {{ wtf.quick_form() }} with this:
<label>{{ form.username.label }}</label>
{{ form.username }}
<label>{{ form.firstname.label }}</label>
{{ form.firstname }}
<label>{{ form.lastname.label }}</label>
{{ form.lastname }}
<div data-toggle="fieldset" id="email-fieldset">
{{ form.email.label }}
<table class="ui table">
<thead>
<th>Network</th>
<th>Address</th>
<th>
{{ form_button(url_for('main.add_email'),
icon ('plus')) }}
</th>
</thead>
<tbody>
{% for e in form.email %}
<tr data-toggle="fieldset-entry">
<td>{{ e.network }}</td>
<td>{{ e.address }}</td>
<td>
{{ form_button(url_for('main.remove_email',
id=loop.index), icon ('remove')) }}
</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
{{ form.submit }}
When I render this, it appears as below in my browser:
This has the virtue of being consistent, but isn't the look I want to get using flask-bootstrap. I'm struggling to figure out which approach will get me where I want to go more easily.
SOLUTION
Changing the form html to this gave me the UI elements I was shooting for. The key was understanding that "class_" could be passed in and would be rendered in the output html as "class".
<div class="form-group required"><label class="control-label">{{ form.username.label }}</label>
{{ form.username(class_='form-control') }}</div>
<div class="form-group required"><label class="control-label">{{ form.firstname.label }}</label>
{{ form.firstname(class_='form-control') }}</div>
<div class="form-group required"><label class="control-label">{{ form.lastname.label }}</label>
{{ form.lastname(class_='form-control') }}</div>
<div data-toggle="fieldset" id="email-fieldset" class="form-group">
{{ form.email.label }}
<table class="ui table">
<thead>
<th>Network</th>
<th>Address</th>
<th>
{{ form_button(url_for('main.add_email'),
icon ('plus')) }}
</th>
</thead>
<tbody>
{% for e in form.email %}
<tr data-toggle="fieldset-entry">
<td>{{ e.network(class_='form-control') }}</td>
<td>{{ e.address(class_='form-control') }}</td>
<td>
{{ form_button(url_for('main.remove_email',
id=loop.index), icon ('remove')) }}
</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
