read_group 方法中的域

Question

有标准方法

 def read_group(self, cr, uid, domain, fields, groupby, offset=0, limit=None, context=None, orderby=False)

我在上面调用一个 super 并传递这样的域

[('end_date', '>=', '2019-05-01'), ('end_date', '<=', '2019-05-30'), ('employee', 'in', [49]), ('state', 'in', ['done'])]

而且有效。

但是当我尝试附加

domain.append(('&'))
domain.append(('state', 'in', ['progress']))

我明白了

File "/home/www/workspace/openerp-7.0-20140804-231303/openerp/osv/expression.py", line 201, in normalize_domain
    assert expected == 0, 'This domain is syntactically not correct: %s' % (domain)
AssertionError: This domain is syntactically not correct: [('end_date', '>=', '2019-05-01'), ('end_date', '<=', '2019-05-30'), ('employee', 'in', [49]), ('state', 'in', ['done']), '&', ('state', 'in', ['progress'])]

基本上，需要按日期和状态 'done' 过滤所有记录，最重要的是状态 'progress'.

中的所有记录

更新。

如果我使用域

domain = [('end_date', '>=', '2019-05-01'), ('end_date', '<=', '2019-05-30'), ('employee', 'in', [49]),
         ('state', 'in', ['done'])]

我得到 3 条记录，

如果我使用

domain = [('employee', 'in', [49]), ('state', 'in', ['progress'])]

我得到了 2 条记录的结果，

但如果我像这样组合这些域，我会得到 0 条记录

domain = [('state', 'in', ['progress']),('end_date', '>=', '2019-05-01'), ('end_date', '<=', '2019-05-30'), ('employee', 'in', [49]),
         ('state', 'in', ['done'])]

我的域应该是什么样子才能获得 5 条记录？

可能的问题是 'progress' 中没有 end_date

的记录

Answer 1

逻辑运算符“&”和“|”有 2 个元数，这意味着 2 个三元组（"normal" 具有 3 个条目的域元组）必须跟在它们后面。您只附加一个三元组。在您的情况下，您可以删除 '&' 的 append，因为不使用任何逻辑运算符，everything/every 三元组将默认与 AND 组合。

逻辑运算符“!”有 arity 1，顺便说一句。

您可以在 the official documentation 中找到足够的信息。

A domain is a list of criteria, each criterion being a triple (either a list or a tuple) of (field_name, operator, value) where:

field_name (str) a field name of the current model, or a relationship traversal through a Many2one using dot-notation e.g. 'street' or 'partner_id.country' operator (str) an operator used to compare the field_name with the value. Valid operators are:

= equals to != not equals to

> greater than

>= greater than or equal to

< less than

<= less than or equal to

=? unset or equals to (returns true if value is either None or False, otherwise behaves like =)

=like matches field_name against the value pattern. An underscore _ in the pattern stands for (matches) any single character; a percent sign % matches any string of zero or more characters.

like matches field_name against the %value% pattern. Similar to =like but wraps value with ‘%’ before matching

not like doesn’t match against the %value% pattern

ilike case insensitive like

not ilike case insensitive not like

=ilike case insensitive =like

in is equal to any of the items from value, value should be a list of items

not in is unequal to all of the items from value

child_of is a child (descendant) of a value record. Takes the semantics of the model into account (i.e following the relationship field named by _parent_name).

Domain criteria can be combined using logical operators in prefix form:

'&' logical AND, default operation to combine criteria following one another. Arity 2 (uses the next 2 criteria or combinations).

'|' logical OR, arity 2.

'!' logical NOT, arity 1.

编辑：即使这应该是另一个问题，我也会尝试解决您的特殊域问题：

[('employee_id', 'in', [49]),
'|',
    ('state', 'in', ['progress']),
    '&', ('state', 'in', ['done']),
        '&', ('end_date', '>=', '2019-05-01'), ('end_date', '<=', '2019-05-30')]

结果应该是（伪）：

EMPLOYEE with ID 49 AND
(STATE is progress OR (STATE is done AND END_DATE is between ...))
