Project Description

Installation

The package is available on PyPI and is tested on Python 2.7 to 3.4

pip install datatables

Usage

Using Datatables is simple. Construct a DataTable instance by passing it your request parameters (or another dict-like object), your model class, a base query and a set of columns. The columns list can contain simple strings which are column names, or tuples containing (datatable_name, model_name), (datatable_name, model_name, filter_function) or (datatable_name, filter_function).

Additional data such as hyperlinks can be added via DataTable.add_data, which accepts a callable that is called for each instance. Check out the usage example below for more info.

Example

models.py

class User(Base):
    __tablename__ = 'users'

    id          = Column(Integer, primary_key=True)
    full_name   = Column(Text)
    created_at  = Column(DateTime, default=datetime.datetime.utcnow)

    # Use lazy=joined to prevent O(N) queries
    address     = relationship("Address", uselist=False, backref="user", lazy="joined")

class Address(Base):
    __tablename__ = 'addresses'

    id          = Column(Integer, primary_key=True)
    description = Column(Text, unique=True)
    user_id     = Column(Integer, ForeignKey('users.id'))

views.py

@view_config(route_name="data", request_method="GET", renderer="json")
def users_data(request):
    # User.query = session.query(User)
    table = DataTable(request.GET, User, User.query, [
        "id",
        ("name", "full_name", lambda i: "User: {}".format(i.full_name)),
        ("address", "address.description"),
    ])
    table.add_data(link=lambda o: request.route_url("view_user", id=o.id))
    table.searchable(lambda queryset, user_input: perform_some_search(queryset, user_input))

    return table.json()

template.jinja2

<table class="table" id="clients_list">
    <thead>
        <tr>
            <th>Id</th>
            <th>User name</th>
            <th>Address</th>
        </tr>
    </thead>
    <tbody>
    </tbody>
</table>

<script>
    $("#clients_list").dataTable({
        serverSide: true,
        processing: true,
        ajax: "{{ request.route_url("data") }}",
        columns: [
            {
                data: "id",
                "render": function(data, type, row){
                    return $("<div>").append($("<a/>").attr("href", row.DT_RowData.link).text(data)).html();
                }
            },
            { data: "name" },
            { data: "address" }
        ]
