Trac Reports = Relatórios Trac

The Trac reports module provides a simple, yet powerful reporting facility to present information about tickets in the Trac database. O módulo de relatórios Trac fornece um simples mas poderoso facilitador de geração de relatórios para apresentar informações sobre tickets no base de dados Trac.

Rather than have its own report definition format, TracReports relies on standard SQL SELECT statements for custom report definition. Ao invés de ter sua própria definição do formato do relatório, TracReports baseia-se na sintaxe padrão SQL SELECT para customizar definições de relatório.

A report consists of these basic parts:

  • ID -- Unique (sequential) identifier
  • Title -- Descriptive title
  • Description -- A brief description of the report, in WikiFormatting text.
  • Report Body -- List of results from report query, formatted according to the methods described below.
  • Footer -- Links to alternative download formats for this report.

Um relatório consiste basicamente em:

  • ID -- Identificador único (sequencial)
  • Title -- Título descritivo
  • Description -- Uma breve descrição do relatório, no texto em formato WikiFormatting.
  • Report Body -- Lista dos resultados da consulta do relatório, formatado de acordo com os métodos descritos abaixo.
  • Footer -- Links para outros formatos de download para este relatório.

Changing Sort Order == == Mudando a ordenação

Simple reports - ungrouped reports to be specific - can be changed to be sorted by any column simply by clicking the column header. Relatórios simples - relatórios não agrupados para ser específico - podem ser mudados para ser ordenado por qualquer coluna simplesmente clicando no cabeçalho da coluna.

If a column header is a hyperlink (red), click the column you would like to sort by. Clicking the same header again reverses the order. Se um cabeçalho da coluna é um hyperlink (vermelho), clique na coluna na qual você deseja ordernar por. Clicando no mesmo cabeçalho novamente, inverte a ordenação.

Alternate Download Formats == Outros Formatos de Download

Aside from the default HTML view, reports can also be exported in a number of alternate formats. At the bottom of the report page, you will find a list of available data formats. Click the desired link to download the alternate report format. Exceto a visualização padrão HTML, relatórios podem também serem exportados em vários formatos alternativos. Na base da página do relatório, você irá achar uma lista de formatos de dados disponíveis. Clique no link desejado para o download do relatório com formato alternativo.

Comma-delimited - CSV (Comma Separated Values) === === Delimitador de Virgulas - CSV(Comma Separated Values)

Export the report as plain text, each row on its own line, columns separated by a single comma (','). Note: Column data is stripped from carriage returns, line feeds and commas to preserve structure. Exporte o relatório em texto-limpo, cada linha na sua própria linha, coluna separado por uma vírgula (','). Nota: O dado de uma coluna é retirado dos caracteres de retorno de linha, próxima linha e vírgulas para preservar a estrutura.

Tab-delimited === === Delimitador-Tab

Like above, but uses tabs (\t) instead of comma. Como acima, mas utiliza o caracter tab (\t) ao invés de vírgula. (',')

RSS - XML Content Syndication === ===RSS - Conteúdo XML para Syndication

All 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. Todos relatórios suportam syndications usando XML/RSS2.0. Para assinar, clique no ícone laranja 'XML' no fim da página. Veja TracRss para informações gerais sobre o suporte RSS no Trac.


Creating Custom Reports == == Criando Relatórios Customizados

Creating a custom report requires a comfortable knowledge of SQL. Criar um relatório customizado necessita um bom conhecimento de SQL.

A report is basically a single named SQL query, executed and presented by Trac. Reports can be viewed and created from a custom SQL expression directly in from the web interface. Um relatório é basicamente uma simples consulta SQL, executado e apresentado por Trac. Relatórios podem ser visualizados e criados de uma expressão SQL customizada diretamente pela interface web.

Typically, a report consists of a SELECT-expression from the 'ticket' table, using the available columns and sorting the way you want it. Basicamente, um relatório consiste de uma expressão SELECT de uma tabela 'ticket', usando colunas disponíveis e ordenando na forma que você desejar.

Ticket columns == == Colunas Ticket

The ticket table has the following columns:

  • id
  • time
  • changetime
  • component
  • severity
  • priority
  • owner
  • reporter
  • cc
  • url
  • version
  • milestone
  • status
  • resolution
  • summary
  • description

Uma tabela ticket contém as seguintes colunas:

  • id
  • time
  • changetime
  • component
  • severity
  • priority
  • owner
  • reporter
  • cc
  • url
  • version
  • milestone
  • status
  • resolution
  • summary
  • description

See TracTickets for a detailed description of the column fields. Veja TracTickets para uma detalhada descrição dos campos da coluna.

all active tickets, sorted by priority and time todos tickets ativos, ordenados por prioridade e tempo

Example: All active tickets, sorted by priority and time Exemplo: Todos tickets ativos, ordenados por prioridade e tempo

SELECT id AS ticket, status, severity, priority, owner, 
       time as created, summary FROM ticket 
  WHERE status IN ('new', 'assigned', 'reopened')
  ORDER BY priority, time

Advanced Reports: Dynamic Variables == == Relatórios Avançados: Variáveis Dinâmicas

For more flexible reports, Trac supports the use of dynamic variables in report SQL statements. In short, dynamic variables are special strings that are replaced by custom data before query execution. Para relatórios mais flexíveis, Trac suporta o uso de variáveis dinâmicas em relatórios de sintaxe SQL. Em poucas palavras, variáveis dinâmicas são strings especiais que são substitídos por dados customizados antes da execução da consulta.

Using Variables in a Query

The syntax for dynamic variables is simple, any upper case word beginning with '$' is considered a variable.

Example:

SELECT id AS ticket,summary FROM ticket WHERE priority='$PRIORITY'

To assign a value to $PRIORITY when viewing the report, you must define it as an argument in the report URL, leaving out the the leading '$'.

Example:

 http://projects.edgewall.com/trac/reports/14?PRIORITY=high

Special/Constant? Variables

There is one magic dynamic variable to allow practical reports, its value automatically set without having to change the URL.

  • $USER -- Username of logged in user.

Example (List all tickets assigned to me):

SELECT id AS ticket,summary FROM ticket WHERE owner='$USER'

Advanced Reports: Custom Formatting

Trac is also capable of more advanced reports, including custom layouts, result grouping and user-defined CSS styles. To create such reports, we'll use specialized SQL statements to control the output of the Trac report engine.

Special Columns

To format reports, TracReports looks for 'magic' column names in the query result. These 'magic' names are processed and affect the layout and style of the final report.

Automatically formatted columns

  • ticket -- Ticket ID number. Becomes a hyperlink to that ticket.
  • created, modified, date, time -- Format cell as a date and/or time.
  • description -- Ticket description field, parsed through the wiki engine.

Example:

SELECT id as ticket, created, status, summary FROM ticket 

Custom formatting columns

Columns whose names begin and end with 2 underscores (Example: _'_color_'_) are assumed to be formatting hints, affecting the appearance of the row.

  • _'_group_'_ -- Group results based on values in this column. Each group will have its own header and table.
  • _'_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.
  • _'_style_'_ -- A custom CSS style expression to use for the current row.

Example: List active tickets, grouped by milestone, colored by priority

SELECT p.value AS __color__,
     t.milestone AS __group__,
     (CASE owner WHEN 'daniel' THEN 'font-weight: bold; background: red;' ELSE '' END) AS __style__,
       t.id AS ticket, summary
  FROM ticket t,enum p
  WHERE t.status IN ('new', 'assigned', 'reopened') 
    AND p.name=t.priority AND p.type='priority'
  ORDER BY t.milestone, p.value, t.severity, t.time

Note: A table join is used to match ticket priorities with their numeric representation from the enum table.

Changing layout of report rows

By default, all columns on each row are display on a single row in the HTML report, possibly formatted according to the descriptions above. However, it's also possible to create multi-line report entries.

  • column_ -- Break row after this. By appending an underscore ('_') to the column name, the remaining columns will be be continued on a second line.
  • _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.
  • _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).

Example: List active tickets, grouped by milestone, colored by priority, with description and multi-line layout

SELECT p.value AS __color__,
       t.milestone AS __group__,
       (CASE owner 
          WHEN 'daniel' THEN 'font-weight: bold; background: red;' 
          ELSE '' END) AS __style__,
       t.id AS ticket, summary AS summary_,             -- ## Break line here
       component,version, severity, milestone, status, owner,
       time AS created, changetime AS modified,         -- ## Dates are formatted
       description AS _description_,                    -- ## Uses a full row
       changetime AS _changetime, reporter AS _reporter -- ## Hidden from HTML output
  FROM ticket t,enum p
  WHERE t.status IN ('new', 'assigned', 'reopened') 
    AND p.name=t.priority AND p.type='priority'
  ORDER BY t.milestone, p.value, t.severity, t.time
