||||
|
||||
 |
||||
|
||||
|
||||
## Modify Share base |

|
||||
- Open Project base |
||||
- Click on 'Share' button on top right tool bar |
||||
- Under 'Shared base link' tab |
||||
- Click on button to copy 'Embeddable HTML code' |
||||
|
||||

||||
|
||||
```html |
||||
<iframe |
||||
class="nc-embed" |
||||
src="https://nocodb-nocodb-rsyir.ondigitalocean.app/dashboard/#/nc/base/e3bba9df-4fc1-4d11-b7ce-41c4a3ad6810?embed" |

||||
style="background: transparent; border: 1px solid #ddd" |
||||
> |
||||
</iframe> |
||||

# Primary Key |
||||
A primary key is a special database table column designated to uniquely identify each table record. |
||||
|
||||
## Use of Primary Key |
||||
As it uniquely identifies an individual record of a table, it is used internally by NocoDB for all operations associated with a record |
||||
|
||||
## Primary Key in NocoDB |
||||
- Primary Key that gets defined / used in NocoDB depends on how underlying table was created. Summary is captured below |
||||
1. From UI, Create new table / Import from Excel / Import from CSV |
||||
1. An `ID` [datatype: Integer] system field created by default during table creation is used as primary key |
||||
2. Additional system fields `created-at`, `updated-at` are inserted by default & can be omitted optionally; these fields can be deleted after table creation |
||||
2. Connect to existing external database |
||||
1. Existing `primary key` field defined for a table is retained as is; NocoDB doesn't insert a new ID field |
||||
2. Additional system fields `created-at`, `updated-at` are not inserted by default |
||||
3. Import from Airtable |
||||
1. Airtable record ID is marked as primary key for imported records, and is mapped to field `ncRecordId` [datatype: varchar] |
||||
2. If a new record is inserted after migration & if ncRecordId field was omitted during record insertion - auto generated string will be inserted by NocoDB |
||||
3. Computed hash value for the entire record is stored in system field `ncRecordHash` |
||||
4. Additional system fields `created-at`, `updated-at` are not inserted by default |
||||
4. Create new table using SDK / API |
||||
1. No default primary key field is introduced by NocoDB. It has to be explicitly specified during table creation (using attribute `pk: true`) |
||||
|
||||
:::info |
||||
**What if Primary Key was missing?** |
||||
|
||||
It is possible to have a table without any primary key. |
||||
- External database table can be created without primary key configuration. |
||||
- New table can be created using SDK / API without primary key |
||||
|
||||
In such scenario's, new records can be created in NocoDB for this table, but records can't be updated or deleted as there is no way for NocoDB to uniquely identify these records |
||||
::: |
||||
|
||||
:::info |
||||
**Can I change the Primary Key to another column within tables?** |
||||
- You can't update Primary Key from NocoDB UI. You can reconfigure it at database level directly & trigger `meta sync` explicitly. |

# Display Value |
||||
|
||||
The `Display Value`, as its name suggests, serves as the primary or main value within a row of a table, and it is typically the attribute by which we identify or associate that specific row. While it is advisable for the display value to be linked to a column with unique identifiers, such as a primary key, it's important to note that this uniqueness is not always enforced at the database level. |
||||
|
||||
## Use of Display Value |
||||
- Within a spreadsheet, `Display Value` are always highlighted so that it is easier to recognise what row we are in. |
||||
- And when `Links` are created between two tables - it is the Display Value that appears in `Linked records` modal. |
||||
|
||||
Example: |
||||
Display Value highlighted in Actor table |
||||
 |
||||
|
||||
Display Value associated when Links field |
||||
The value shown in `Link Records` modal when adding a new link is associated records `Display value` |
||||
|
||||
 |
||||
|
||||
|
||||
## Set Display Value |
||||
Click dropdown icon (🔽) in the target column. Click `Set as Display Value`. |
||||
|
||||
 |
||||
|
||||
:::info |
||||
How is Display Value identified for existing database tables ? |
||||
- It is usually the first column after the primary key which is not a number. |
||||
- If there is no column which is not a number then the column adjacent to primary key is chosen. |
||||
|
||||
Can I change the Display Value to another column within tables ? |
||||
- Yes, you can use the same way mentioned above to set Display Value. |

||||
--- |
||||
|
||||
## Overview |
||||
|
||||
Expanded Form allows you to edit a row data in a form. Apart from record information, it also consists of the activity feed such as user comments or revision history. |
||||
|
||||
 |
||||
|
||||
## Expanding a Record |
||||
|
||||
To expand a record in a grid view, click on double arrow icon that appears on the first column on hover over a record. |
||||
|
||||
 |
||||
|
||||
Alternatively, we can click on a cell and press the space bar. The expanded form for the corresponding record will be opened. |
||||
|
||||
## Activity Feed |
||||
|
||||
In an expanded form comment section, disable `Comments only` checkbox to show the activity feed. |
||||
|
||||

`View` often represents a way to display your data. NocoDB provides different types of views to display your data in different ways. You can also Sort or Filter records within a View. Each View is independent, which means the configuration applying to View 1 will not apply to View 2. |
||||
|
||||
## View Types |
||||
|
||||
### Grid View |
||||
|
||||
Grid View, as a default type of view, allows you to display your data in a spreadsheet-like interface. |
||||
|
||||
 |
||||
|
||||
### Form View |
||||
|
||||
Form View allows you to arrange fields in a form to input data. |
||||
|
||||
 |
||||
|
||||
You can drag-drop columns from the form to form-field-menu-bar as required. |
||||
|
||||
### Gallery View |
||||
|
||||
Gallery View allows you to display images as thumbnails with other fields just like a gallery. |
||||
|
||||
 |
||||
|
||||
### Kanban View |
||||
|
||||
Kanban View allows you to visualise your data using cards at various stacks. |
||||
|
||||
 |
||||
|
||||
## View Permission Types |
||||
|
||||
We can apply permission to each View. By default, Collaborative Views will be used. To see or change the view type, expand `view-tool-bar-menu` as shown below. |
||||
|
||||
 |
||||
|
||||
### Collaborative Views (default) |
||||
- Collaborators with edit permissions or higher can change the view configurations |
||||
|
||||
### Locked Views |
||||
- No one can edit view configurations until it is Unlocked |
||||
- All collaborators can only READ data from such views |
||||
|
||||
### Personal Views |
||||
- Only you can edit the view configuration. |
||||
- Your personal views are hidden for other collaborators |
||||
- Are not available currently; will be enabled in future release |
