HTML table representation for SQLAlchemy .
Assume you have an entity called Music. It looks like the below.
class Music(Base):
id = Column(Integer, primary_key=True)
name = Column(Unicode, nullable=False)The following code renders a sortable <table> consisting of a list of music.
from dodotable.schema import Table, Column
table = Table(
cls=Music,
label='music table',
columns=[
Column(attr='id', label=u'id', order_by='id.desc'),
Column(attr='name', label=u'name'),
],
sqlalchemy_session=session
)
print(table.select(offset=0, limit=10).__html__())Using with Flask
Flask uses Jinja2 as the template engine. As they mentioned on
document[1]_, it is one of strategy that implement __html__ on every class
inherit dodotable.schema.Renderable to convert a instance into HTML
directly in Jinja2. Re-write the example written before with Flask.
from dodotable.schema import Table, Column
from flask import Flask, render_template, request
app = Flask(__name__)
@app.route('/musics/', methods=['GET'])
def list_musics():
table = Table(
cls=Music,
label='music table',
columns=[
Column(attr='id', label=u'id',
order_by=request.args.get('order_by')),
Column(attr='name', label=u'name'),
],
sqlalchemy_session=session
)
return render_template(
'list_musics.html',
table=table.select(limit=request.args.get('limit'),
offset=request.args.get('offset'))
)And list_musics.html which is jinja2 template is look like below.
<html>
<body>
{{ table }}
</body>
</html>
