  • TracReports

    v1 v2  
    33for presenting information about tickets from the Trac database.
     5Rather than have its own report format, TracReports relies on standard SQL
     6SELECT statements for custom report definition.
     8A report consists of these basic parts:
     9 * ID -- Unique (sequential) identifier
     10 * Title  -- Descriptive title
     11 * Description  -- A brief description of the report, in WikiFormatting text.
     12 * Report Body -- List of results from report query, formatted according to the methods described below.
     13 * Footer -- Links to alternative download formats for this report.
     16== Alternate Download Formats ==
     17Aside from the default HTML view, reports can also be exported in a number of alternate formats.
     18At the bottom of the report page, you will find a list of available data formats. Click the desired link to
     19download the alternate report format.
     21=== Comma-delimited - CSV (Comma Separated Values) ===
     22Export the report as plain text, each row on its own line, columns separated by a single comma (',').
     23'''Note:''' Column data is stripped from carriage returns, line feeds and commas to preserve structure.
     25=== Tab-delimited ===
     26Like above, but uses tabs (\t) instead of comma.
     28=== RSS - XML Content Syndication ===
     29All reports support syndication using XML/RSS 2.0. To subscribe to a , click the the orange 'XML' icon at the bottom of the page. See TracRss for general information on RSS support in Trac.
     31== Changing Sort Order ==
     32Simple reports - ungrouped reports to be specific - can be changed to be sorted by any column simply by clicking the column header.
     34If a column header is a hyperlink (red), click the column you would like to sort by. Clicking the same header again reverses the order.
    537== Creating Custom Reports ==
    1648== Ticket columns ==
    17 The '''ticket'' table has the following columns:
     49The ''ticket'' table has the following columns:
    1850 * id
    1951 * time
    2658 * cc
    2759 * url
    28  * version -- Version of the project does this ticket pertains to.
     60 * version
    2961 * milestone
    3062 * status
    3567See TracTickets for a detailed description of the column fields.
    37 == Special Columns ==
    38 To format the report properly, Trac needs to know the meaning of some result
    39 columns . This is a list of column names of special meaning to Trac:
    40  * '''ticket''' -- Ticket ID number. Will become a hyperlink to that ticket.
    42 ''Note: In upcoming releases, there will be more special columns added, to create color-coded reports, grouping and other nifty features.''
    46 == Sample Reports ==
    47 '''status and summary for all tickets'''
    49 {{{
    50 SELECT id as ticket, status, summary FROM ticket
    51 }}}
    53 ----
    5469'''all active tickets, sorted by priority and time'''
     71'''Example:''' ''All active tickets, sorted by priority and time''
    5773SELECT id AS ticket, status, severity, priority, owner,
    64 '''active tickets, grouped by milestone and sorted by priority'''
     83== Advanced Reports: Dynamic Variables ==
     84For more flexible reports, Trac supports the use of ''dynamic variables'' in report SQL statements.
     85In short, dynamic variables are ''special'' strings that are replaced by custom data before query execution.
     87=== Using Variables in a Query ===
     88The syntax for dynamic variables is simple, any upper case word beginning with '$' is considered a variable.
    67 SELECT id AS ticket, milestone, status, severity,
    68        priority, component, owner, summary
    69   FROM ticket
    70   WHERE status IN ('new', 'assigned', 'reopened')
    71   ORDER BY milestone,
    72     (CASE priority
    73       WHEN 'highest' THEN 0
    74       WHEN 'high' THEN 1
    75       WHEN 'normal' THEN 2
    76       WHEN 'low' THEN 3
    77       ELSE 4
    78     END), severity, time
     92SELECT id AS ticket,summary FROM ticket WHERE priority='$PRIORITY'
     95To assign a value to $PRIORITY when viewing the report, you must define it as an argument in the report URL, leaving out the the leading '$'.
     103=== Special/Constant Variables ===
     104There is one ''magic'' dynamic variable to allow practical reports, its value automatically set without having to change the URL.
     106 * $USER -- Username of logged in user.
     108Example (''List all tickets assigned to me''):
     110SELECT id AS ticket,summary FROM ticket WHERE owner='$USER'
     117== Advanced Reports: Custom Formatting ==
     118Trac is also capable of more advanced reports, including custom layouts,
     119result grouping and user-defined CSS styles. To create such reports, we'll use
     120specialized SQL statements to control the output of the Trac report engine.
     122== Special Columns ==
     123To format reports, TracReports looks for 'magic' column names in the query
     124result. These 'magic' names are processed and affect the layout and style of the
     125final report.
     127=== Automatically formatted columns ===
     128 * '''ticket''' -- Ticket ID number. Becomes a hyperlink to that ticket.
     129 * '''created, modified, date, time''' -- Format cell as a date and/or time.
     130 * '''description''' -- Ticket description field, parsed through the wiki engine.
     134SELECT id as ticket, created, status, summary FROM ticket
     137=== Custom formatting columns ===
     138Columns whose name begins and ends with '__' (Example: '''__color__''') are
     139assumed to be ''formatting hints'', affecting the appearance of the row.
     141 * '''___group___''' -- Group results based on values in this column. Each group will have its own header and table.
     142 * '''___color___''' -- Should be a numeric value ranging from 1 to 5 to select a pre-defined row color. Typically used to color rows by issue priority.
     143 * '''___style___''' --- A custom CSS style expression to use for the current row.
     145'''Example:''' ''List active tickets, grouped by milestone, colored by priority''
     147SELECT p.value AS __color__,
     148     t.milestone AS __group__,
     149     (CASE owner WHEN 'daniel' THEN 'font-weight: bold; background: red;' ELSE '' END) AS __style__,
     150 AS ticket, summary
     151  FROM ticket t,enum p
     152  WHERE t.status IN ('new', 'assigned', 'reopened')
     153    AND AND p.type='priority'
     154  ORDER BY t.milestone, p.value, t.severity, t.time
     157'''Note:''' A table join is used to match ''ticket'' priorities with their
     158numeric representation from the ''enum'' table.
     160=== Changing layout of report rows ===
     161By default, all columns on each row are display on a single row in the HTML
     162report, possibly formatted according to the descriptions above. However, it's
     163also possible to create multi-line report entries.
     165 * '''column_''' -- ''Break row after this''. By appending an underscore ('_') to the column name, the remaining columns will be be continued on a second line.
     167 * '''_column_''' -- ''Full row''. By adding an underscore ('_') both at the beginning and the end of a column name, the data will be shown on a separate row.
     169 * '''_column'''  --  ''Hide data''. Prepending an underscore ('_') to a column name instructs Trac to hide the contents from the HTML output. This is useful for information to be visible only if downloaded in other formats (like CSV or RSS/XML).
     171'''Example:''' ''List active tickets, grouped by milestone, colored by priority, with  description and multi-line layout''
     174SELECT p.value AS __color__,
     175       t.milestone AS __group__,
     176       (CASE owner
     177          WHEN 'daniel' THEN 'font-weight: bold; background: red;'
     178          ELSE '' END) AS __style__,
     179 AS ticket, summary AS summary_,             -- ## Break line here
     180       component,version, severity, milestone, status, owner,
     181       time AS created, changetime AS modified,         -- ## Dates are formatted
     182       description AS _description_,                    -- ## Uses a full row
     183       changetime AS _changetime, reporter AS _reporter -- ## Hidden from HTML output
     184  FROM ticket t,enum p
     185  WHERE t.status IN ('new', 'assigned', 'reopened')
     186    AND AND p.type='priority'
     187  ORDER BY t.milestone, p.value, t.severity, t.time
