The data source is a required part of the report object. Flexmonster supports data from OLAP data sources, SQL databases, CSV and JSON static files, and inline JSON data. Each data source requires specific properties to be set inside the dataSource section of the report object. Read more in the following sections:
JSON data source can be:
Here is a list of dataSource properties used to connect to JSON data sources:
browseForFile – Boolean. Defines whether you want to load the file from the local file system (true) or not (false). Default value: false.
data (from v2.2) – JSON. The inline JSON data.type – String. The type of data source. In this case, it is "json". You do not need to explicitly define this property when reading static JSON files with a “.json” extension.filename – String. The URL to the file or to the server-side script which generates data. mapping (optional) – Mapping Object | String. Allows defining field data types, captions, and multi-level hierarchies, grouping fields under separate dimensions, and setting other view configurations of hierarchies. It can be either the inline Mapping Object or the URL to a JSON file with mapping. See an example on JSFiddle. requestHeaders (optional) – Object. This object allows you to add custom request headers. The object consists of "key": "value" pairs, where "key" is a header name and "value" is its value. Check out a live sample on JSFiddle. Important note: requestHeaders is not saved when obtaining the report via save() and getReport() API calls. useStreamLoader (optional) – Boolean. Optimizes the large file processing using the stream loader. When set to true, the stream loader is enabled. Available only when loading files via URL. See an example on JSFiddle. Default value: false. Here is an example of JSON data set using a file from the local file system:
{
dataSource: {
/* Path to the local JSON file */
filename: "data.json"
}
}
If the data is generated by a server-side script, type must be defined explicitly:
{
dataSource: {
type: "json",
filename: "script_which_returns_json_data"
}
}
Inline JSON:
{
dataSource: {
/* jsonData variable contains JSON data */
data: jsonData
}
}
CSV data source can be:
Here is a list of dataSource properties used to connect to CSV data sources:
browseForFile – Boolean. Defines whether you want to load a file from the local file system (true) or not (false). Default value: false.type – String. The type of data source. In this case, it is "csv". You do not need to explicitly define this property when reading static CSV files with a .csv extension.fieldSeparator – String. Defines the specific fields separator to split each CSV row. There is no need to define it if the CSV fields are separated by , or ;. This property is required only if another character separates fields. For example, if you use TSV, where a tab character is used to separate fields, then the fieldSeparator parameter should be set to "\t". thousandSeparator (optional) – String. Allows importing CSV data with commas used to separate groups of digits in numbers (e.g., 1,000 for one thousand). To load such data, set thousandSeparator to ",". filename – String. The URL to the file or to the server-side script which generates data.ignoreQuotedLineBreaks (from v2.1) – Boolean. Indicates whether line breaks in quotes should be ignored (true) or not (false). When set to true, CSV parsing is faster. Set it to false only if your data source has important line breaks in quotes. Note that this might slow down CSV parsing a little bit. Default value: true.mapping (optional) – Mapping Object | String. Allows defining field data types, captions, and multi-level hierarchies, grouping fields under separate dimensions, and setting other view configurations of hierarchies. It can be either the inline Mapping Object or the URL to a JSON file with mapping. See an example on JSFiddle. requestHeaders (optional) – Object. This object allows you to add custom request headers. This object consists of "key": "value" pairs, where "key" is a header name and "value" is its value. Check out a live sample on JSFiddle. Important note: requestHeaders is not saved when obtaining the report via save() and getReport() API calls.In the following example data is taken from a CSV file where the colon character (:) is used to separate fields within the row. Line breaks in quotes are not ignored:
{
dataSource: {
/* URL or local path to a CSV file */
filename: 'colon-data.csv',
fieldSeparator: ':',
ignoreQuotedLineBreaks: false
}
}
If the data is generated by a server-side script, type must be defined explicitly:
{
dataSource: {
type: "csv",
filename: "script_which_returns_csv_data"
}
}
Here is a list of dataSource properties used to connect to SQL databases using the custom data source API:
type – String. The type of data source. In this case, it is "api".url – String. The path to the API endpoints.index – String. The data set identifier.mapping (optional) – Mapping Object | String. Allows defining field data types, captions, and multi-level hierarchies, grouping fields under separate dimensions, and setting other view configurations of hierarchies. It can be either the inline Mapping Object or the URL to a JSON file with mapping. See an example on JSFiddle. requestHeaders (optional) – Object. This object allows you to add custom request headers. This object consists of "key": "value" pairs, where "key" is a header name and "value" is its value. Check out a live sample on JSFiddle. Important note: requestHeaders is not saved when obtaining the report via save() and getReport() API calls. withCredentials (optional) – Boolean. It indicates whether cross-site Access-Control requests should be made using credentials such as authorization headers (true) or not (false). For more details refer to MDN web docs.withCredentials flag to true is recommended when using Windows authentication and other types of server authentications. When set to false, the browser does not request credentials, as well as does not include them into outgoing requests. Default value: false.
Here is an example of how a connection to a relational database is represented in a dataSource object:
{
dataSource: {
type: "api",
url: "http://olap.flexmonster.com:9202/api/cube",
index: "fm-product-sales"
}
}

A comma-delimited list of predefined roles to connect to a server or a database using the permissions defined by that role. If this property is omitted, all roles are used and the effective permissions are the combination of all roles. For example, to combine "admin" and "manager" roles, set the roles property like so: roles: "admin,manager".subquery (optional) – String. The parameter to set a server-side filter to decrease the size of the response from the OLAP cube. For example, to show reports for only one specific year set the subquery like so: "subquery": "select {[Delivery Date].[Calendar].[Calendar Year].&[2008]} on columns from [Adventure Works]".requestHeaders (optional) – Object. This object allows you to add custom request headers. This object consists of "key": "value" pairs, where "key" is a header name and "value" is its value. Check out a live sample on JSFiddle.

}
}
Try the example on JSFiddle.
Use the Connect option to choose another data source or Open to load another report at runtime. Use Save to save the report with the current data source.
Data in the pivot table will be updated and saved within the report.
The API calls connectTo(), load(), and open() are used to change the data source at runtime. The API call save() is used to save the report.
