dm 1.0.0

Features

  • New dm_gui() for interactive editing of dm objects (#1076, #1319).

  • dm_apply_filters(), dm_apply_filters_to_tbl() and dm_get_filters() are deprecated (#424, #426, #1236).

  • dm_disambiguate_cols() adds table names as a suffix by default, and gains a .position argument to restore the original behavior. Arguments sep and quiet are renamed to .sep and .quiet (#1293, #1327).

  • dm_squash_to_tbl() is deprecated in favor of the new .recursive argument to dm_flatten_to_tbl(). Arguments start and join are renamed to .start and .join (#1272, #1324).

  • dm_rm_tbl() is deprecated in favor of dm_select_tbl() (#1275).

  • dm_bind() and dm_add_tbl() are deprecated in favor of dm() (#1226).

dm 0.2.1

Breaking changes

  • dm_get_all_fks() has been optimized for speed and no longer sorts the keys (#560).
  • dm operations are now slightly faster overall.

Internal

  • The internal data structure for a dm object has changed to accommodate foreign keys to other columns than the primary key. An upgrade message is shown when working with a dm object from an earlier version, e.g. if it was loaded from a cache or an .rds file (#402).
  • Drop "dm_v1" class from dm objects again, this would have made every S3 dispatch more costly. Relying on an internal "version" attribute instead (#547).

dm 0.2.0

Breaking changes

  • *_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).

  • 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).

  • A dm object is defined using a nested tibble, one row per table (#57).

dm 0.0.3

  • cdm_enum_pk_candidates() and cdm_enum_fk_candidates() both show candidates first (#85).
  • cdm_flatten_to_tbl() works only in the immediate neighborhood (#75).
  • New cdm_squash_to_tbl() implements recursive flattening for left, inner and full join (#75).
  • Updated readme and introduction vignette (#72, @cutterkom).
  • New cdm_check_constraints() to check referential integrity of a dm (#56).
  • cdm_copy_to() gains table_names argument (#79).
  • check_key() now deals correctly with named column lists (#83).
  • Improve error message when calling cdm_add_pk() with a missing column.

dm 0.0.2.9003

  • Fix R CMD check.

dm 0.0.2.9002

  • Use caching to improve loading times.
  • Run some tests only for one source (#76).
  • cdm_enum_fk_candidates() checks for class compatibility implicitly via left_join().
  • cdm_enum_fk_candidates() contains a more detailed entry in column why if no error & no candidate (percentage of mismatched vals etc.).
  • Improve error messages for cdm_join_to_tbl() and cdm_flatten_to_tbl() in the presence of cycles or disconnected tables (#74).

dm 0.0.2.9001

  • Remove the src component from dm (#38).
  • Internal: Add function checking if all tables have same src.
  • Internal: Add 2 classed errors.
  • cdm_get_src() for local dm always returns a src based on .GlobalEnv.
  • cdm_flatten() gains ... argument to specify which tables to include. Currently, all tables must form a connected subtree rooted at start. Disambiguation of column names now happens after selecting relevant tables. The resulting SQL query is more efficient for inner and outer joins if filtering is applied. Flattening with a right_join with more than two tables is not well-defined and gives an error (#62).
  • Add a vignette for joining functions (#60, @cutterkom).
  • Shorten message in cdm_disambiguate_cols().

dm 0.0.2.9000

  • cdm_flatten_to_tbl() disambiguates only the necessary columns.
  • When flattening, the column name of the LHS (child) table is used (#52).
  • Fix formatting in enum_pk_candidates() for character data.
  • cdm_add_pk() and cdm_add_fk() no longer check data integrity by default.
  • Explicitly checking that the join argument is a function, to avoid surprises when the caller passes data.
  • cdm_copy_to() works correctly with filtered dm objects.
  • cdm_apply_filters() actually resets the filter conditions.
  • A more detailed README file and a vignette for filtering (#29, @cutterkom).
  • cdm_draw() no longer supports the table_names argument, use cdm_select_tbl().
  • Copying a dm to a database now creates indexes for all primary and foreign keys.

dm 0.0.2

Breaking changes

  • Requires tidyr >= 1.0.0.
  • cdm_nrow() returns named list (#49).
  • Remove cdm_semi_join().
  • Remove cdm_find_conn_tbls() and the all_connected argument to cdm_select() (#35).
  • Unexport cdm_set_key_constraints().
  • Rename cdm_select() to cdm_select_tbl(), now uses {tidyselect}.
  • cdm_nycflights13() now has cycle = FALSE as default.
  • Rename cdm_check_for_*() to cdm_enum_*().

Performance

  • cdm_filter() only records the filtering operation, the filter is applied only when querying a table via tbl() or when calling compute() or the new cdm_apply_filters() (#32).

New functions

  • New cdm_flatten_to_tbl() flattens a dm to a wide table with starting from a specified table (#13). Rename cdm_join_tbl() to cdm_join_to_tbl().
  • New cdm_disambiguate_cols() (#40).
  • New cdm_rename() (#41) and cdm_select() (#50) for renaming and selecting columns of dm tables.
  • New length.dm() and length<-.dm() (#53).
  • $, [[, [, names(), str() and length() now implemented for dm objects (read-only).
  • New enum_pk_candidates().

Minor changes

  • browse_docs() opens the pkgdown website (#36).
  • as_dm() now also accepts a list of remote tables (#30).
  • Use {tidyselect} syntax for cdm_rename_tbl() and cdm_select_tbl() (#14).
  • The tibbles returned by cdm_enum_fk_candidates() and cdm_enum_pk_candidates() contain a why column that explains the reasons for rejection in a human-readable form (#12).
  • Improve compatibility with RPostgres.
  • create_graph_from_dm() no longer fails in the presence of cycles (#10).
  • Only suggest {RSQLite}.
  • cdm_filter() no longer requires a primary key.
  • decompose_table() adds the new column in the table to the end.
  • tbl() now fails if the table is not part of the data model.

Documentation

  • Add setup article (#7).

Internal

  • Using simpler internal data structure to store primary and foreign key relations (#26).
  • New nse_function() replaces h() for marking functions as NSE to avoid R CMD check warnings.
  • Simplified internal data structure so that creation of new operations that update a dm becomes easier.
  • When copying a dm to a database, NOT NULL constraints are set at creation of the table. This removes the necessity to store column types.
  • Using {RPostgres} instead of {RPostgreSQL} for testing.
