changelog:v0-28-medium-changes,changelog,v0-28-medium-changes,Medium changes,"Datasette now conforms to the  Black coding style  ( #449 ) - and has a unit test to enforce this in the future 
                     
                     
                         
                             
                                 New  Special table arguments : 
                                 
                                     
                                         
                                             ?columnname__in=value1,value2,value3  filter for executing SQL IN queries against a table, see  Table arguments  ( #433 ) 
                                         
                                         
                                             ?columnname__date=yyyy-mm-dd  filter which returns rows where the spoecified datetime column falls on the specified date ( 583b22a ) 
                                         
                                         
                                             ?tags__arraycontains=tag  filter which acts against a JSON array contained in a column ( 78e45ea ) 
                                         
                                         
                                             ?_where=sql-fragment  filter for the table view  ( #429 ) 
                                         
                                         
                                             ?_fts_table=mytable  and  ?_fts_pk=mycolumn  query string options can be used to specify which FTS table to use for a search query - see  Configuring full-text search for a table or view  ( #428 ) 
                                         
                                     
                                 
                             
                         
                     
                     
                         You can now pass the same table filter multiple times - for example,  ?content__not=world&content__not=hello  will return all rows where the content column is neither  hello  or  world  ( #288 ) 
                     
                     
                         You can now specify  about  and  about_url  metadata (in addition to  source  and  license ) linking to further information about a project - see  Source, license and about 
                     
                     
                         New  ?_trace=1  parameter now adds debug information showing every SQL query that was executed while constructing the page ( #435 ) 
                     
                     
                         datasette inspect  now just calculates table counts, and does not introspect other database metadata ( #462 ) 
                     
                     
                         Removed  /-/inspect  page entirely - this will be replaced by something similar in the future, see  #465 
                     
                     
                         Datasette can now run against an in-memory SQLite database. You can do this by starting it without passing any files or by using the new  --memory  option to  datasette serve . This can be useful for experimenting with SQLite queries that do not access any data, such as  SELECT 1+1  or  SELECT sqlite_version() .","[""Changelog"", ""0.28 (2019-05-19)""]","[{""href"": ""https://github.com/python/black"", ""label"": ""Black coding style""}, {""href"": ""https://github.com/simonw/datasette/pull/449"", ""label"": ""#449""}, {""href"": ""https://github.com/simonw/datasette/issues/433"", ""label"": ""#433""}, {""href"": ""https://github.com/simonw/datasette/commit/583b22aa28e26c318de0189312350ab2688c90b1"", ""label"": ""583b22a""}, {""href"": ""https://github.com/simonw/datasette/commit/78e45ead4d771007c57b307edf8fc920101f8733"", ""label"": ""78e45ea""}, {""href"": ""https://github.com/simonw/datasette/issues/429"", ""label"": ""#429""}, {""href"": ""https://github.com/simonw/datasette/issues/428"", ""label"": ""#428""}, {""href"": ""https://github.com/simonw/datasette/issues/288"", ""label"": ""#288""}, {""href"": ""https://github.com/simonw/datasette/issues/435"", ""label"": ""#435""}, {""href"": ""https://github.com/simonw/datasette/issues/462"", ""label"": ""#462""}, {""href"": ""https://github.com/simonw/datasette/issues/465"", ""label"": ""#465""}]"
