need help with filter

[manh7890]

i see in the filter you warp all the filter and the or to a combination is there a way i could write a query like SELECT * FROM "users" WHERE ("users"."username" LIKE '%ass%' AND "users"."username" LIKE '%John%' AND "users"."username" LIKE '%Doe%') OR "users"."username" LIKE '%a%' OR "users"."username" LIKE '%n%' LIMIT 10 with two or more 'or' i want to select some name and get all the name that match one of my filter

All possible combinations are described in the readme here.

If both "filter" and "or" are present, then they are interpreted as a combination of two AND groups compared with each other using OR:

?filter=age||$eq||50&filter=name||$cont||Jack&or=name||$cont||John&or=name||$cont||Doe

WHERE ((age = 50 AND name LIKE "%Jack%") OR (name LIKE "%John%" AND name LIKE "%Doe%"))

I don't think you can generate a SQL query like the one you want using this library.

Just to make sure I understand the goal of your SQL query: you want to search for a user that has a username containing multiple search criteria? (Contains "John" AND contains "Doe")

You may modify the "$cont" operator to take multiple criteria into account instead of only one:

filter.Operators["$cont"] = &filter.Operator{
	Function: func(tx *gorm.DB, f *filter.Filter, column string, dataType filter.DataType) *gorm.DB {
		if dataType != filter.DataTypeText && dataType != filter.DataTypeEnum {
			return f.Where(tx, "FALSE")
		}
		groupCondition := tx.Session(&gorm.Session{NewDB: true})
		for _, a := range f.Args {
			query := castEnumAsText(column, dataType) + " LIKE ?"
			value := "%" + sqlutil.EscapeLike(a) + "%"
			groupCondition = f.Where(groupCondition, query, value)
		}
		return tx.Where(groupCondition)
	},
	RequiredArguments: 1,
}

And that would be used like so:

?filter=username||$cont||John,Doe  -> WHERE (username LIKE "%John%" AND username LIKE "%Doe%")
