Configuration

  • AppConfig.setMaxGroups Sets the maximum amount of groups the user is able to create.
  • AppConfig.setMaxConditions Sets the maximum amount of conditions the user is able to create.

Terminology

Angular Query Builder differentiates between SearchContainer, Group, Condition, SourceType, SourceField, ComparisonOperator, LogicalOperator and InputItem. Each object can be dynamically defined within the $scope of the AngularJS controller.

  • SearchContainer can contain one or multiple Group.
  • Group consists of a SourceType, LogicalOperator and one or multiple Condition.
  • Condition consists of a SourceField, ComparisonOperator and an InputItem.
  • SourceType basically represents the source to be searched. It is possible to define multiple SourceType but in most cases one is sufficient. The SourceType object consists of the following keys:
    • name is a string
    • displayName is a string
    • sourceFields is an array of SourceField objects
  • SourceField defines the available options for the first dropdown element of each Condition. The SourceField object consists of the following keys:
    • name is a string
    • displayName is a string
    • comparisonOperators is an array of ComparisonOperator objects
  • ComparisonOperator defines the available options for the second dropdown element of each Condition. The ComparisonOperator object consists of the following keys:
    • name is a string
    • displayName is a string
  • LogicalOperator defines how each Condition in a Group should be logically connected. The LogicalOperator object consists of the following keys:
    • name is a string
    • displayName is a string
  • InputItem contains the data entered by the user. The InputItem object consists of the following keys:
    • data is a string
    • displayName is a string
