nicain / dataframe-browser Goto Github PK

Home page for DFB should either immediately construct a new session if it doesn't have one, or the first request that requires a session should construct a new one.

Currently hard-coded to nicholasc-ubuntu:5050, needs to be more general

Source of major slowdowns

The dataframebrowser module contains the class DataFrameBrowser, which is now essentially the controller. merge these togeher, and potentially gut the remaining functionality of the controller

High priority for end-user testing

Get rid of search, and replace with dropdown

A result of refactor. To repro bookmark a table, move away from it, then select from menu, and try to apply action

Currently held at http://nicholasc-ubuntu:5001/browser/03ac90e9cd0948e08036bd90384da97b/

To reproduce, load csv, then from cursor object c.data.shape

Greyed out, or simply not there

In order to parallelize calls to mappers in /lazy_loading, need to factor the mapper_library_dict off of DataFrameBrowser instance. Need to rip this completely off.

xref #1, because ripping the mapper dictionary off of the DataFrameBrowser instance also allows for a single cache location, instead of per-instance caching.

Should be relatively easy

To reproduce, make a page, bookmark it, and then go to its permalink, and then try to access the bookmark

Currently cached on server view:

https://github.com/nicain/dataframe-browser/blob/3c538859619dd98766dc6a03899b46d2221c3dea/dataframe_browser/view.py#L48

makes more sense to cache as an action per-frame, but hold in a generic data store and implement a back-end like simple dictionary or redis server

This was never a design consideration, but now that an index column can be specified, this might be nice to figure out

Probably need to gut the socket.io functionality.

Also seems to slow down responsiveness.

See miguelgrinberg/Flask-SocketIO#35

Libraries:

• jquery
• popper
• bootstrap
• dataTables
• socket.io
• bokeh/bokeh-widgets/bokeh-tables
• open-iconic-bootstrap
• copy-to-clipboard button

• Append session uuid to browser endpoint
• Front landing page at /index

When a new session is launched, many people just stared at the blank screen instead of getting started with stuff. Need basic instructions when model.active is root

Some people might not know what the default password is, so I can put it in with pgpass

Embed action with dropdown to supply a copy-paste block for setting a jupyter notebook kernel to node

COuld you please generalize this as a kwargs for browser? Thanks!!

• Fix the loading of images
• Devise test to ensure future stability of feature
• Rebase master

Need to generalize the saving of the cursor to support python 2 and 3, and serve through separate endpoints

When a fully-specified path is used to display a node, a change in the active session will force a refresh of the url. This wont change the content on the page that is at the path, but a refresh will occur to the content. Turn this off with a freeze boolean served from the server

To facilitate sharing of analysis work-product, need endpoints that provide access to results. Need integration with bookmarks. Facilitates embediing in other services via CORS.

• Non-interactive template served from URI.
• Permalink button on browser
• New flask endpoints to serve bookmarks and uniquely identified point

This will make more sense from a user perspective

Requires patch bump

Using CORS to serve lazy_loading; decouple mappers completely to make a mapper service.

• Remove imports of mapper_library_dict from main library/app
• Add endpoint on mapper service to get available mappers as json
• Hook it together.

Eventually might make a separate package for mappers, and add selector for possible mapper source servers.

If I enter data into the "Read Query" form, it should persist the next time I visit that form since I am likely to want to iterate on the query a few times.

It appears as f dill is not necessary, and I can just pickle the class directly

should be called active; need to un-remove it, and session scope it it it was not done already.

Best candidate so far for re-working unit tests.

Does this make sense to change?

necessary to keep track of rollout

Right now, client.data is a property on client. it would be nice to have a gititem and setitem interface
