such situation. This has been modified specifically for the children
under the schema, and catalog nodes.
Also, override the Backform.Control.prototype.render function to allow
to provide the control data to the evaluable functions (i.e. disabled,
visible, required).
with schema specified object name. This will also works with
EntepriseDB's package too.
Also, added dependency on the current connection object, it will allow
us to use the keywords list specific to the database server in futuer.
You can use the qtIdent template filter as:
conn|qtIdent(name)
or,
conn|qtIdent(schema_name, name)
of (label, value) tuple in the SelectControl.
We will apply the transform function, while rendering the control, and
not during intialization. This will allow us to generate different
options data based on the dependent values.
inputs.
In order to do the proper quoting around the identifier, different type,
and literal, we introduced respective functions qtIdent, qtTypeIdent,
qtLiteral in psycopg2 driver. Also, introduced them as the Jinja's
custom filter for using it directly inside the templates.
Also, created an utility - generate_keywords.py in order to generate
keyword lists from the latest PostgreSQL installation.
create/edit mode. It will fetch the modified sql using the 'msql' url
specific to that node.
Also, modified by Ashesh before committing it.
i.e. Added code comments, cleanup code for the control, etc.
- Fixed the server backend version check for any schema object.
- Fixed the switch control, it was not enable to toggle the values properly.
- Fixed the editableCell to work properly in the collection properties.
boolean values. (Modified quite a lot by Ashesh, before committing).
This patch also allow to set the header class in the backgrid through
setting 'cellHeaderClass' property of the schema object for any of the
node. It will allow us to set the different behaviour of the cell in the
list. One of the test case for it is: this will allow us to set the
different width of each column in the list using CSS class(es).
Introduced a new ajax function to return the HTTP Status code 410 (GONE).
Changed the location of the javascript from each modules, it loads.
Added .swp, .swo files in the .gitignore file
- Renamed the URL 'nodes' to 'children', because - we'll return the
children for the current node.
- Using the URL 'nodes' to fetch all nodes of its type, when not
specified the node-id, otherwise regenerate that node info using the
node-id (it will be used by the refresh function).
- Added the URL 'msql' for fetching modified SQL for the modified
objects.
- Separated the URL 'deps' (GET/POST methods) to 'dependency' and
'dependent', because - it will be used to fetch the properties of the
object, not manipulate it. (as suggested by Dave).
This commit includes the changes related to it in the specific nodes.
(i.e. server-group, and server).
Also, includes a javascript change to ask the user (if they really want
to leave the page, and it is not an accidental navigation by keyboard
shortcuts).
- Allow to release connection using the database OID (did).
- Generate correct url for the collection nodes.
- Removed the server-type from the collection node module, from the
generate_browser_collection_node(...) function.
- Show version string, and not version integer in the server properties
(when connected).
Also, resolved an issue related showing the correct server variant in
properties dialog, it is a regression introduced by the patch server
version check.
i.e.
'server-connect' and 'server-disconnected' events will be generated
while server gets connected and disconnected respectively.
For demo purpose - listening to the server connection from the test
script.
connect to the database server. Also, added modified the way, we do
check the node is supported by the server.
Instead of creating separate blueprint for the server types, they will
be independently works. In order to add different variant of the
PostgreSQL, we need to extend the ServerType class, and override the
'instanceOf' function for identification using version string. Please
take a look at the ppas.py for the example.
During checking the back-end support for the node, we will also check
the server type (variant) along with the version within the range of
maximum and minimum version for the node. And, the same support added
for the schema attributes in front-end (JavaScript).
Really thankful to Khushboo Vashi for her initial work in front-end. I
took it further from there.

1. Update correct variable for database information in the connection

2. Raise exception, when database not found, instead of return the

manager, once the connection to the maintenance database has been made,
because - we will have did (i.e. Database OID) most of the time for the
any node, and not its name as identifier.
This will allow us to work directly with OID, and we will not need to
bother about renaming of the database name.
during undo-redo action. Also, resolved the focus losing issue, which
closing the subnode editor using undo action.
Also, resolved an issue related to 'beforeopen' failed on server node,
due to api changes on tree events.
i.e. Switch between the tabs, opening/closing the subnode in edit mode.
Also, removed the Save, Cancel buttons from the subnode editor, it was
looking very redudant. Ctrl+Z for undo, Ctrl+Shift+Z/Ctrl+Y for Redo
shortcut will be good enough for undoing all the changes in the
properties panel.
creation, and editing within the properties panel infrastructure.
We do use the backgrid.js for listing the subnode collection, and for
editing/creating new object for the subnode, we do use the same
infrastructure using the backform.
server connection.
The BaseDriver and BaseConnection are two abstract classes, which allows
us to replace the existing driver with the currently used. The current
implementation supports to connect the PostgreSQL and Postgres Plus
Advanced Server using the psycopg2 driver.
it causes an issue performing DDL operations without sending DML to the
database, flush(..) does the job for us, it sends those operations to
the database without committing it.
And, this was causing the issue in current implemenation, while setting
'Administrator' role to the given email-id after the create_role, and
create_user operations during setup.
(tabbed) UI.
Also, fixed few bugs pointed by Dave:
* Open the URL in separate browser tab/window.
* Fixed few CSS changes for look and feel for the dialog view
* Some of the panels were not listed in the context menu for the
wcDocker.
(lazy loading) using the require.js. This allows us to load the
javascript required for any node, only when it was loaded in the browser
tree. Also, introduced the mechanism to show/edit/create of any node in
a tab panel (wcDocker.Panel).
PostgreSQL node(s).
Browser Tree Node (PostgreSQL object) requires more than just CRUD.
i.e.
- CRUD (Create, Read, Update & Delete)
- Reversed Engineered SQL for the object
- Modified Query in edit mode
i.e. ALTER TABLE ...
- Statistics
- List of dependents
- List of dependencies
- Children node list
This class can be inherited to achieve the different routes for each of
the object types/collections.
OPERATION | URL | Method
---------------+------------------------+--------
List | /obj/[Parent URL]/ | GET
Properties | /obj/[Parent URL]/id | GET
Create | /obj/[Parent URL]/ | POST
Delete | /obj/[Parent URL]/id | DELETE
Update | /obj/[Parent URL]/id | PUT
SQL (Reversed | /sql/[Parent URL]/id | GET
Engineering) |
SQL (Modified | /sql/[Parent URL]/id | POST
Properties) |
Statistics | /stats/[Parent URL]/id | GET
Dependencies | /deps/[Parent URL]/id | GET
Dependents | /deps/[Parent URL]/id | POST
Children Nodes | /nodes/[Parent URL]/id | GET
NOTE:
Parent URL can be seen as the path to identify the particular node.
i.e.
In order to identify the TABLE object, we requires information
about the server -> database -> schema objects.
Hence, the Parent URL for the TABLE object will be something like
this as below:
<int:sid>/<str:database>/<str:schema>
Inherited a new classes ServerGroupView and ServerView, which are
inherited from the NodeView for the implementation of above operations.
submodules inherited from the PgAdminModule instead of regular
Blueprint. This allows us to load the module automatically from the
under the pgadmin directory, and will work to extend the pgAdmin
extension module.
PgAdminModule is inherited from the Blueprint, and bring several
methods:
- get_own_stylesheets, which returns the stylesheets used by the module
(excluding its submodules stylesheets)
- get_own_javascripts
- menu_items, which returns a dictionray mapping the old hook names
(context_items etc) to a list of MenuItem instances
For more specialized modules (as for now, any module that should be part
of the browser tree construction), one can define an abstract base class
defining additional methods.
For example, the BrowserPluginModule abstract base class defines the
following methods:
- jssnippets
- csssnipeets
- node_type
- get_nodes
The File menu now includes a "Create" submenu, and Delete/Rename
options. Nodes can offer Delete/Rename functionality, and the
options on the menu are automatically enabled/disabled based on
the selected node. Each node can also offer Create functionality,
and specify a list of node types (including itself) from which the
option should be made available. The menu is dynamically generated
based on the selected node.
The Context menu on the treeview works in a similar way, except that
nodes can offer any context menu items (we don't allow this on the
top menu, as that should stay consistent to avoid user confusion).
This allows us to update the configuration database schema as needed,
and use the setup script to update it to the current version.
NOTE: Existing databases will need to be recreated once following
this commit. It doesn't seem worth handling the "upgrade from v0"
case when I'm probably the only active developer right now.
This commit adds the following:
- Storage of server groups in the configuration database
- Creation of a default server group on in the database
- A mechanism for plugging in treeview node types
- A node type for server groups with:
- Treeview display
- Custom per-node javascript implementing a menu option/dialogue to add new groups
- Custom per-node CSS to style the treeview node
- JSON formatted data in response to AJAX requests, including:
- Success/failure indication
- Error message
- Extra info (e.g. stack trace)
- The original request data
- Additional return data, e.g. node ID and label etc.
Still needs some work to:
- Minimise AJAX calls by writing multiple settings at once.
- Move the settings storage/retrieval JS code into a global file
- Avoid using synchronous AJAX calls in the main thread
This adds bootstrap-dialog to help with creation of nice dialogs,
and adds the ability for modules to render Javascript into the
browser, and specify onclick handlers in the menu system.
Also add a basic About dialog, using the new infrastructure and
showing some useful info about the application.
Modules may now include functions that return lists of menu items
that will be included on the main browser window menu. While we're
at it, move the test views into a separate module.
This uses a single default user in the config database, which is
auto-logged into the app when SERVER_MODE = False. In this mode we
also hide/remove user-related functions in the UI.
A user authentication module based on flask-security is added, which
allows users to login and change/recover passwords etc. Custom templates
are included for the user/password UIs.
A new setup script will initialise the user (and later settings) DB,
adding the first user and granting them an Administrator role.
A redirects blueprint module is added to handle simple URL redirects.
A browser module is added and currently renders a skeleton page with
a menu bar, gravatar and jumbotron.
NOTE FOR LATER: Currently this code might make the nice basis for any
web app that needs user management and plugins. Hmmm....
instead. Add support to the runtime to allow the user to specify the
Python path. This needs to be more automated for release, but will be
useful for debugging and development.
Upon startup, the runtime will attempt to locate pgAdmin4.py in a
number of different relative locations. Once found, it will execute
it in a new thread. The main window is then created and the brower's
initial page is set to the root of the CherryPy server. At present,
that's http://127.0.0.1:8080.
