EditRowPlugin
Replacement for some of EditTablePlugin, some of EditTablerowPlugin and some of TablePlugin.
Features:
- You can edit one row, or even one cell at a time, instead of having to edit the entire table.
- Supports footer rows.
- Supports sorting columns in tables using Javascript, avoiding the round-trip to the server required by TablePlugin.
- Simple interface to moving rows around in the table, deleting and adding rows.
- Gets row numbering right (takes account of headers).
- It's much faster than the individual plugins it replaces.
- (geeky) Coded using a clean object-oriented architecture, which makes it easily extensible.
- (geeky) Uses a simple REST interface for saving changes, which allows Javascript table editors to use the same interface to save.
- (geeky) Tolerant to Javascript being disabled in the browser
Note that this plugin is designed for use with tables of up to ~1000 rows. Tables
larger than this will work, but they put considerable stress on the browser
and the server. For manipulating larger tables, you are recommended to investigate
Foswiki:Extensions.JQGridPlugin.
Usage
Works like the EditTablePlugin (it uses exactly the same
%EDITTABLE
macro)
and you can use it to edit the entire table, or just one row at a time.
An
%EDITTABLE{...}%
in the topic will be associated with the next table
in the topic. If there is no existing table, or another
%EDITTABLE{...}%
is seen before the next table, then a new table will
be created.
Parameters:
-
format
- The format of the cells in a row of the table. The format is defined like a table row, where the cell data specify the type for each cell. For example, format="| text,16 | label |"
. Cells can be any of the following types:
-
text, <size>, <initial value>
Simple text field. Initial value is optional.
-
textarea, <rows>x<columns>, <initial value>
Multirow text box. Initial value is optional.
-
select, <size>, <option 1>, <option 2>, etc
Select one from a list of choices.
-
radio, <size>, <option 1>, <option 2>,
etc. Radio buttons. size
indicates the number of buttons per line in edit mode.
-
checkbox, <size>, <option 1>, <option 2>, etc
Checkboxes. size
indicates the number of buttons per line in edit mode.
-
label, 0, <label text>
Fixed label.
-
row
The row number, automatically worked out.
-
date, <size>, <initial value>, <DHTML date format>
Date. Initial value and date format are both optional.
-
changerows
- Rows can be added and removed if "on"
. Rows can be added but not removed if "add"
. Defaults to the value of the preference CHANGEROWS
, or "on"
if it isn't set.
-
disable
- By default, the plugin shows both full table and individual row editing controls. You can choose to disable one or both of these modes using the disable
parameter, by setting it to row
or full
(or row,full
to disable all editing and just leave sorting). If full table editing is disabled, but changerows
is on
, then the (edit table) button will be replaced with a (add row) button. Defaults to the value of the preference EDITROWPLUGIN_DISABLE
, or none
if it isn't set.
-
buttons
- set to left
(the default) or right
to position edit controls in the first or last columns in the table. buttons="right"
may be required if you are using other plugins that expect a certain column order.
-
quietsave
- Quiet Save button is shown if "on"
. Defaults to the value of the preference QUIETSAVE
, or off
if it isn't set.
-
include
- Name of another topic defining the EDITTABLE parameters. The first %EDITTABLE% in the topic is used. This is useful if you have many topics with the same table format and you want to update the format in one place.
-
headerrows
- Number of rows to treat as headers. Header rows are not editable, and will not be sorted. headerislabel
is also supported for EditTablePlugin compatibility (equivalent to headerrows="1"
) |
-
header
- Specify the single-row header format of a new table. For example, "|*Food*|*Drink*|"
. Provided to allow you to create a new table in a document, and to have a header that is truely readonly.
-
footerrows
- Number of rows to treat as footers. Footer rows are not editable and will not be sorted. |
-
orientrowedit
- unique to EditRowPlugin, this parameter controls the orientation of a row when it is being edited. It can be set to horizontal
(the default) or vertical
, which will present the columns of the row as rows in the editor. This makes editing very wide tables much easier. Has no effect in whole table editing mode.
-
helptopic
Topic name containing help text shown when editing a table. The %STARTINCLUDE% and %STOPINCLUDE% markers can be used in the topic to specify what is shown. Note that newlines are removed from the included text so the that text can be used inside a table.
-
js
gives local, per-table control over the EDITROWPLUGIN_JS
preference described below.
Table rows are shown with a row edit button
in the first column,
and a table edit button
after the
table. When the table is
edited, then a number of buttons may be shown depending on the
settings of
changerows
and
quietsave
.
- saves the changes
- saves without notification
- adds a new row after the current row, taking for its contents the initial values specified in the EDITTABLE macro
- deletes the row
- Move this row up one row in the table
- Move this row down one row in the table
- cancels the open edit
Per Cell Settings
An individual edit field type can be defined for each individual table cell. Place an
%EDITCELL{ "type, ..." }%
macro at the end of the cell content. This is useful to override the per column
%EDITTABLE{ format="..." }%
settings, or to create tables with key/value rows. All edit field types of the
format="..."
parameter are supported. For example, to define a text field, type:
| cell content %EDITCELL{ "text, 20" }% |
Note: The
%EDITCELL{}%
macro cannot be used by itself; place an
%EDITTABLE{ }%
macro at the beginning of a table where you want to use
%EDITCELL{ }%
macros.
Examples
Copy the following examples and paste them into a topic in the Sandbox web
(or another web where you have write access). The EditRowPlugin is
not enabled on this site, so the examples will be disabled.
Example 1
%EDITTABLE{ format="| row, -1 | text, 20, init | select, 1, not started, starting, ongoing, completed | radio, 3,:-),:-I,:-( | date, 20 |" changerows="on" quietsave="on"}%
| *Nr* | *Project* | *State* | *Progress* | *Timestamp* |
| 1 | Sliced yoghourt | completed | :-) | 26 Jun 2002 |
| 2 | Cubical turkeys | not started | :-( | 27 Oct 2007 |
| 3 | Self-eating burritos | ongoing | :-D | 1 Apr 2008 |
| 4 | Unified field theory | completed | :-) | 1 Apr 2012 |
Example 2
%EDITTABLE{ format="| label,12 | textarea, 3x30 |" }%
| *Model* | *Description* |
| 345TG66 | Short, with sightly concave upper surface, and devilish nuts |
| 9A-11 | A new model for 2007, but not quite as pretty as the 9A-10 |
| RR717-D | Solid performer, dependable in vacuum grinders |

Example 4
%EDITTABLE{ format="| label | text, 40 |" }%
|*Key*|*Value*|

Javascript Editing
%EDITTABLE{ format="| text,12 | textarea, 3x30 |" js="assumed"}%
When a table is editable and Javascript is enabled, then when the user rolls the mouse over a table row:
- individual table cells have a yellow stain on the corner that can be clicked to open an in-place editor,
- table rows that contain at least one editable cell can be manually sorted using drag-and-drop, by dragging the (though beware that a
TABLE
tag with an initsort
will override this, which can be confusing),
Table columns can be sorted in the browser, by clicking the heading above the row.
Note that javascript editing is automatically disabled if:
- The current user does not have CHANGE access to the topic
- No user is logged in, but the
rest
script is listed in the {AuthScripts}
admin setting.
Preferences
The plugin interprets a couple of
preferences, in common with the EditTablePlugin.
QUIETSAVE |
Gives a default value for the quietsave parameter. Default is off . |
CHANGEROWS |
Gives a default value for the changerows parameter. Default is on . |
Also, the plugin has a couple of its own settings:
EDITROWPLUGIN_JS |
Usually the plugin expects to be able to use Javascript to generate controls. However sometimes users disable Javascript in the browser, so the plugin also generates a minimal set of fallback controls to give non-JS access to the main features, even if Javascript is disabled. You can use this preference to control whether Javascript is preferred, ignored, or assumed when generating the controls.-
preferred means "use JS if it's available, but keep the non-JS fallback controls visible", -
ignored means "never use JS, only display the non-JS controls", -
assumed means "assume that JS will be available in the browser, and don't display the fallback controls". You can control the setting on a per-table basis using the js parameter to the EDITTABLE macro. |
EDITROWPLUGIN_DISABLE |
Set to on to disable the plugin. Default is off . |
These preferences can be defined in
SitePreferences, in WebPreferences for an individual web, or in the topic.
There is also a
configure
(expert) setting that allows you to change the name of the macro used to carry table editor parameters. This is usually
EDITTABLE
but can be changed to help work around problems with other plugins.
Installation Instructions
You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.
Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".
If you have any problems, or if the extension isn't available in
configure
, then you can still install manually from the command-line. See
http://foswiki.org/Support/ManuallyInstallingExtensions for more help.
Using the REST API
The plugin provides a couple of useful
REST handlers. Javascript developers may find
this API useful when developing their own tools that
manipulate tables.
There are two entry points,
get
and
save
. The
get
handler can be used to retrieve the contents of
a table. Parameters are:
-
erp_topic
the web.wikiname of the topic
-
erp_table
the table (numbered from 1)
-
erp_row
- the row (numbered from 1)
-
erp_col
- the column (numbered from 1)
The handler returns a row, a column, or the entire table depending on the presence of the
erp_row
and
erp_col
parameters. If neither is given, the entire table is returned. If only
erp_row
is given, just that row will be returned, etc. The data is returned in JSON format.
For example, a URI to retrieve column 2 from the table
EDITTABLE_1
from this topic would look like this:
https://nkwiki.de/foswiki/bin/rest/EditRowPlugin/get?erp_topic=System.EditRowPlugin;erp_table=EDITTABLE_1;erp_col=2
The
save
handler is used to save cells, and accepts the following parameters:
-
erp_topic
the web.wikiname of the topic to be changed
-
erp_table
the table to be changed (numbered from 1)
-
erp_row
- the row to be changed (numbered from 1, or -1 for the whole table)
-
saveRowCmd.x
- if nonzero, this is a save
-
saveRowQuietlyCmd.x
- if nonzero, this is a quietsave
-
upRowCmd.x
- if nonzero, this is a row move
-
downRowCmd.x
- if nonzero, this is a row move
-
deleteRowCmd.x
- if nonzero, this is a row deletion
-
cancelCmd.x
- if nonzero, this is a cancel
-
noredirect
- if set, suppresses the redirect and gets a status code instead
The value of each individual cell is stored in a parameter called
erp_<table>_<row>_<column>
Relationship to other plugins
EditTablePlugin
At this time most features of EditTablePlugin are supported. Known exceptions
are:
- the
editbutton
parameter,
- Plugin preferences (though global preferences are compatible)
TablePlugin
Javascript sorting in EditRowPlugin is much faster than TablePlugin. However
TablePlugin has many features this plugin does not support. For the most part,
the two plugins can safely be used together.
However if you use a TABLE statement with
an
initsort
parameter, it is likely to cause great confusion, as the table will be
re-sorted each time a row is opened for edit, and when the table is edited in full table
mode.
EditTablerowPlugin
Provides the vertical row editing interface like
EditTablerowPlugin, with the row being edited shown in context in the table.
