Flask-sqlalchemy列别名用于浏览器输出 [英] Flask-sqlalchemy column alias for browser output

问题描述

我正在使用for循环来输出单个数据库行的列和值.一切正常，但是有几个问题.列名不适合在浏览器中输出，因此我正在寻找一种关联别名的方法(不确定这是正确的术语)

I'm using a for loop to output the columns and values of a single database row. This is all working but there are a couple of issues. The column names aren't suitable to output in the browser so I'm looking for a way to associate an alias (not sure this is the correct term)

例如列名称:

cust_name
cust_area

所需的输出:

Customer name
Customer area

models.py

models.py

class Customers(db.Model):
    id = db.Column(db.Integer, primary_key = True)
    cust_name = db.Column(db.String(64))
    cust_area = db.Column(db.String(64))
    cat_id = db.Column(db.Integer(8), index = True)

views.py

customer = Customers.query.filter_by(cat_id = page).first()
test_dict = dict((col, getattr(test, col)) for col in test.__table__.columns.keys())
return render_template('test.html',
    customer = test_dict
    )

test.html

test.html

{% for key, value in customer.items() %}
    {{ key }} : {{ value }}
{% endfor %}

谢谢！

推荐答案

使用然后您可以遍历以下列:

Then you could iterate through columns like following:

customer = Customers.query.filter_by(cat_id=page).first()
data = dict((c.info.get('name', c.name), getattr(customer, c.name))
            for c in customer.__table__.c)
# Or using dict comprehension syntax (Python 2.7+).
data = {c.info.get('name', c.name): getattr(customer, c.name)
        for c in customer.__table__.c}
