discoverFields()
discoverFields(
resource):Promise<object>
Function should go over all columns of table defined in resource.table and try to guess data and constraints for each columns. Type should be saved to:
- AdminForthResourceColumn.type Constraints:
- AdminForthResourceColumn.required
- AdminForthResourceColumn.primaryKey For string fields:
- AdminForthResourceColumn.maxLength For numbers:
- AdminForthResourceColumn.min
- AdminForthResourceColumn.max
- AdminForthResourceColumn.minValue, AdminForthResourceColumn.maxValue, AdminForthResourceColumn.enum, AdminForthResourceColumn.foreignResource, AdminForthResourceColumn.sortable, AdminForthResourceColumn.backendOnly, AdminForthResourceColumn.masked, AdminForthResourceColumn.virtual, AdminForthResourceColumn.components, AdminForthResourceColumn.allowMinMaxQuery, AdminForthResourceColumn.editingNote, AdminForthResourceColumn.showIn, AdminForthResourceColumn.isUnique, AdminForthResourceColumn.validation) Also you can additionally save original column type to AdminForthResourceColumn._underlineType. This might be later used in IAdminForthDataSourceConnector.getFieldValue and IAdminForthDataSourceConnector.setFieldValue methods.
