Filters Building Skill

Filter Types Quick Reference

type FilterType =
  | "simple-select"              // Constants (single)
  | "multi-select"               // Constants (multiple)
  | "model-select"               // Model relationship (small lists)
  | "model-multi-select"         // Model relationships (small lists)
  | "model-search-select"        // Model relationship (large lists)
  | "model-search-multi-select"  // Model relationships (large lists)
  | "text"                       // Text input
  | "email"                      // Email input
  | "number"                     // Number input
  | "checkbox"                   // Boolean 0/1
  | "date-range"                 // Date range picker
  | "gap";                       // Visual spacing

Field Definition

Field can be string OR object:

// Simple string - used for all three
field: "organization_id"

// Complex object for custom queries
field: {
  queryParam: "organization_type_id",       // URL query param
  postgresColumn: "organizations.type",     // Postgres column
  elasticsearchColumn: "organization_type_id" // ES column
}

Supported Query Patterns

?name=john

WHERE account.name = 'john'

?name[]=john&name[]=jane

WHERE account.name IN('john','jane')

?not:name=john

WHERE account.name != 'john'

?q:name=john

WHERE LOWER(account.name) ILIKE '%john%'

?gt:age=25

WHERE account.age > 25

?lt:age=65

WHERE account.age < 65

?between:age=25|65

WHERE account.age >= 25 AND account.age <= 65

Gap (Section Separator)

{
  type: "gap",
  placeholder: "",
  label: "Organization Filters",
  field: "",
}

Text Filter

{
  placeholder: "Search Name",
  type: "text",
  field: "name", // Uses q:name for ILIKE search
}

Checkbox Filter

{
  placeholder: "Is Active",
  type: "checkbox",
  field: "is_active",
  checkedValue: "1",
  uncheckedValue: "",
}

Simple Select (Constants)

import { constants } from "@/models/constants";

{
  placeholder: "Status",
  type: "simple-select",
  field: "status",
  options: constants.asset.status,
}

Multi Select (Constants)

{
  placeholder: "Organization Type",
  type: "multi-select",
  field: {
    queryParam: "organization_type_id",
    postgresColumn: "organizations.type",
    elasticsearchColumn: "organization_type_id",
  },
  options: constants.organization.type,
}

Model Select (Small Lists)

For < 50 options:

{
  placeholder: "Organization",
  type: "model-select",
  field: "organization_id",
  modelName: "organization",
  modelDisplayField: "label",
  modelSearchFilters: { disabled: "0" },
}

Model Multi Select (Small Lists)

{
  placeholder: "Tags",
  type: "model-multi-select",
  field: "tag_ids",
  modelName: "tag",
  modelDisplayField: "label",
  modelSearchFilters: { disabled: "0" },
}

Model Search Select (Large Lists)

For > 50 options:

{
  placeholder: "Organization",
  type: "model-search-select",
  field: "organization_id",
  modelName: "organization",
  modelDisplayField: "label",
  modelSearchParam: "q",
  modelSearchFilters: { disabled: "0" },
}

Model Search Multi Select (Large Lists)

{
  placeholder: "Organizations",
  type: "model-search-multi-select",
  field: "organization_id",
  modelName: "organization",
  modelDisplayField: "label",
  modelSearchParam: "q",
  modelSearchFilters: { disabled: "0" },
}

Date Range Filter

{
  placeholder: "Created Date",
  type: "date-range",
  field: "created_at",
}

Complete Example

import { IFilterField } from "@/ui/common/components/types/filters";
import { constants } from "@/models/constants";

export const assetFilters: IFilterField[] = [
  // Section 1: Basic Filters
  {
    placeholder: "Search Name",
    type: "text",
    field: "name",
  },
  {
    placeholder: "Status",
    type: "multi-select",
    field: "status",
    options: constants.asset.status,
  },
  {
    placeholder: "Is Active",
    type: "checkbox",
    field: "is_active",
    checkedValue: "1",
    uncheckedValue: "",
  },

  // Gap for visual separation
  {
    type: "gap",
    placeholder: "",
    label: "Organization Filters",
    field: "",
  },

  // Section 2: Relationships
  {
    placeholder: "Organization",
    type: "model-search-multi-select",
    field: "organization_id",
    modelName: "organization",
    modelDisplayField: "label",
    modelSearchParam: "q",
    modelSearchFilters: { disabled: "0" },
  },
  {
    placeholder: "Organization Type",
    type: "multi-select",
    field: {
      queryParam: "organization_type_id",
      postgresColumn: "organizations.type",
      elasticsearchColumn: "organization_type_id",
    },
    options: constants.organization.type,
  },

  // Gap for dates section
  {
    type: "gap",
    placeholder: "",
    label: "Date Filters",
    field: "",
  },

  // Section 3: Dates
  {
    placeholder: "Created Date",
    type: "date-range",
    field: "created_at",
  },
];

Best Practices

1. Group related filters with

   gap

   separators
2. Use search variants for lists > 50 items
3. Always use

   label

   as modelDisplayField (modify model if needed)
4. Always use

   q

   as modelSearchParam for consistency
5. Add modelSearchFilters to exclude disabled/archived records
6. Use field objects only when postgres/ES columns differ from query param
7. Constants are model-specific:

   constants.{model}.{field}

text

email

number

checkbox

date-range

simple-select

multi-select

model-select

model-multi-select

model-search-select

model-search-multi-select

Key Rules

1. Use gaps to separate logical filter sections
2. Model filters should always filter out disabled records
3. Use search variants for better UX with large datasets
4. Field objects allow custom query building (see Go controller docs)
5. Keep placeholder text concise and descriptive
