Add data to BSON conditionally

[Paulo Coutinho]

Hi,

I want add data to BSON conditionally.

Like this pseudo-code:

var conditions := {}


if (hasPost('name'))
{
    conditions  += bson.M{ name: post('name') }
}


if (hasPost('name'))
{
    conditions  += bson.M{ name: post('name') }
}


var results := findAll(conditions)

I dont know how i can add where/order/sort conditions progressively. 

Can anyone help me with this?

var conditions bson.M

if hasPost('name') {

    conditions['name'] = post('name')

}

No man,

I want add conditions and query parts to mgo. Like equals, $gte, sort, select, but inside each if condition.

For filtering, add entries to the map:

conditions = bson.M{}

if ... {

    conditions["name"] = name

}

if ... {

    conditions["age"] = bson.M{"$gte": 15}

}

Then run Find to obtain a query

q := collection.Find(conditions)

Then you can modify the query to do sorting, selection, etc.

if ... {

    q = q.Sort("age")

}

if ... {

    q = q.Select("name", "age")

}
