dm 0.2.0

Breaking changes

• Deprecate dm_get_src() tbl.dm(), src_tbls.dm(), copy_to.dm(). These functions have better alternatives and use the notion of a "data source" which is being phased out of dplyr (#527).
• *_pk() and *_fk() functions gain an ellipsis argument that comes before check, force and rm_referencing_fks arguments (#520).

Features

• dm_add_pk() and dm_add_fk() support compound keys via the c() notation, e.g. dm_add_pk(dm, table, c(col1, col2)). dm_nycflights13() returns a data model with compound keys by default. Use compound = FALSE to return the data model from dm v0.1.13 or earlier (#3).
• dm_get_all_fks() includes parent_pk_cols column that describes the primary key columns of the parent table (#335).
• dm_from_src() supports the schema argument also for MariaDB and MySQL databases (#516).
• dm objects now inherit from "dm_v1" in addition to "dm", to allow backward-compatible changes of the internal format (#521).
• Use hack to create compound primary keys on the database (#522).
• dm_examine_constraints() and other check functions count the number of rows that violate constraints for primary and foreign keys (#335).
• copy_dm_to(set_key_constraints = FALSE) downgrades unique indexes to regular indexes (#335).
• rows_truncate() implemented for data frames (#335).
• dm_enum_fk_candidates() enumerates column in the order they apper in the table (#335).

dm 0.1.13

Features

• dm_draw() gains column_types argument, if TRUE the column type is shown for each displayed column (#444, @samssann).
• copy_dm_to() gains schema argument (#432).
• dm_from_src() gains dbname argument for MSSQL (#472).

Bug fixes

• Fix rows_update() when multiple columns are updated (#488, @samssann).

Performance

• enum_fk_candidates() now only checks distinct values, this improves performance for large tables. As a consequence, only the number of distinct values is reported for mismatches, not the number of mismatching rows/entries (#494).

Documentation

• Fix description of filtering behavior in ?dm_zoom_to (#403).

Internal

• Move repository to https://github.com/cynkra/dm (#500).
• Enable more Postgres tests (#497).

dm 0.1.12

• dm_from_src() gains dbname argument for MSSQL (#472).
• Implement count() and tally() for dplyr 1.0.3 compatibility (#475).
• Use databases.pacha.dev instead of db-edu.pacha.dev (#478, @pachamaltese).

dm 0.1.10

dm 0.1.9

• New vignette("howto-dm-copy", package = "dm") and vignette("howto-dm-rows", package = "dm") discuss updating data on the database. In part derived from vignette("howto-dm-db", package = "dm") (#411, @jawond).
• New dm_mutate_tbl() (#448).
• dm_financial() falls back to db-edu.pacha.dev if relational.fit.cvut.cz is unavailable (#446, @pachamaltese).
• Use testthat 3e (#455).

dm 0.1.7

• Bump RMariaDB required version to 1.0.10 to work around timeout with R CMD check.
• dm_from_src() accepts schema argument for MSSQL databases (#367).

dm 0.1.6

Breaking changes

• dm_get_src() returns NULL for local data sources (#394).
• Local target in copy_dm_to() gives a deprecation message (#395).

Features

• copy_dm_to() gives a better error message for bad table_names (#397).
• dm objects with local data sources no longer show the "Table source" part in the output.
• Error messages now refer to "tables", not "elements" (#413).
• New dm_bind() for binding two or more 'dm' objects together (#417).

Bug fixes

• For databases, the underlying SQL table names are quoted early to avoid later SQL syntax errors (#419).
• dm_financial() no longer prints message about learn_keys = FALSE.
• dm_rows_update() and related functions now use the primary keys defined in x for establishing matching rows.

Internal

• Use withCallingHandlers() where appropriate (#422).
• Consistent definition of .dm and .zoomed_dm methods (#300).
• Examples involving dm_financial() are not run if connection can't be established (#418).
• Fix database tests on CI (#416).

• Errors regarding cycles in the relationship graph now show the shortest cycle (#405).
• Implement rows_truncate() for databases.
• collect() works on a zoomed dm, with a message.
• The data model is drawn in a more compact way if it comprises of multiple connected components.
• dm_add_pk(check = TRUE) gives a better error message.

Bug fixes

• rows_insert() works if column names consist of SQL keywords (#409).
• Cycles in other connected components don't affect filtering in a cycle-free component.
• Avoid src_sqlite() in examples (#372).

Internal

• Testing SQLite, Postgres and SQL Server on GitHub Actions (#408, @pat-s).
• Testing packages with all "Suggests" uninstalled.

dm 0.1.4

Features

• New dm_rows_insert(), dm_rows_update(), dm_rows_patch(), dm_rows_upsert(), dm_rows_delete() and dm_rows_truncate(), calling the corresponding rows_*() method for every table (#319).

• New rows_truncate() (#319).

• Added rows_insert() and rows_update() methods for SQLite, Postgres, MariaDB and MSSQL (#319).

• Missing arguments now give a better error message (#388).

• Empty dm object prints as dm() (#386).
