opCharts 4.4.2

We are providing ways for customers to produce custom form schema which can be read by certain components in opCharts to show additional fields which can be configured to the users liking.

These files are stored in conf/form_schemas and are json encoded schema which will tell our form system how to render.

Currently there is no way to get dynamic data for helping drive select lists for example but this could change in the future, let us know what you want to see.

Supported opCharts Components

    "label": "Demo",
    "description": "Demo form schema",
    "component": ["element_lists"],
    "tags": ["inventory"],
    "schema": {
        "demo1": {
            "label": "My Label",
            "type": "Text"
        "demo2": {
            "label": "Another Label",
            "type": "Select",
            "options": ["option1", "option2"]


The Filename must be prefixed with the application name, eg opCharts_

The filename must have .json at the end and only be a-Z 0-9 ascii characters.

Part of the filename will be saved to schema documents so changing the filename at a later date will break linkage.

Supported Field Types

Schema Value


requiredChecks the field has been filled in.
numberChecks it is a number, allowing a decimal point and negative values.
rangeChecks it is a number in a range defined by min and max options. Message if it is not a number can be set with the numberMessage option.
emailChecks it is a valid email address.
urlChecks it is a valid URL.
matchChecks that the field matches another. The other field name must be set in the field option.
regexpRuns a regular expression. Requires the regexp option, which takes a compiled regular expression or a string value. Setting the match option to false ensures that the regexp does NOT pass.

See Backbone Form Validation for examples and further docs.
