Children of this class are expected to define a `collection_key` and `key`. - `collection_key`: Usually a plural noun by convention (e.g. `entities`); used to refer collections in both URL's (e.g. `/v3/entities`) and JSON objects containing a list of member resources (e.g. `{'entities': [{}, {}, {}]}`). - `key`: Usually a singular noun by convention (e.g. `entity`); used to refer to an individual member of the collection.

Given an example collection where `collection_key = 'entities'` and `key = 'entity'`, the following URL's could be generated. By default, the URL will represent a collection of entities, e.g.:: /entities If kwargs contains an `entity_id`, then the URL will represent a specific member, e.g.:: /entities/{entity_id} :param base_url: if provided, the generated URL will be appended to it N� z/%s�%s_id)�collection_keyr �key)r# �base_urlr r5 Z entity_idr r r � build_url s zCrudManager.build_urlc C sR |� � �� D ]@\}}|du r(|�|� q t|t�r |�|� t|�|d| < q |S )z Drop null values and handle ids.Nrb )�copyrZ �pop� isinstance�Resourcer )r# r rd �refr r r �_filter_kwargs" s zCrudManager._filter_kwargsc K s, | � |�}| �| jf i |��| j|i| j�S rJ )rl r@ rf rd �r# r r r r �create- s �zCrudManager.createc K s$ | � |�}| �| jf i |��| j�S rJ )rl r: rf rd rm r r r r 4 s �zCrudManager.getc K s | � |�}| �| jf i |���S rJ )rl r? rf rm r r r r< : s zCrudManager.headc K s8 | � |�}| �d| jf d|i|��t�|�d� | j�S )zmList the collection. :param base_url: if provided, the generated URL will be appended to it �%(base_url)s%(query)sre �re �query)rl r9 rf r �build_query_paramrc �r# re r r r r rL > s ��zCrudManager.listc K s$ | � |�}| �| jf d|i|���S )zkUpdate an element. :param base_url: if provided, the generated URL will be appended to it re )rl rC rf rs r r r rA L s zCrudManager.putc K sD | � |�}|�� }|�d| j � | �| jf i |��| j|i| j�S )Nrb )rl rg rh rd rE rf )r# r �paramsr r r �updateU s �zCrudManager.updatec K s | � |�}| �| jf i |���S rJ )rl rG rf rm r r r rF _ s �zCrudManager.deletec K s� | � |�}| �d| jf d|i|��dt�|� d� | j�}t|�}|dkrjd| jj|f }t � d|��n|dkrzt j �n|d S d S ) z�Find a single item with attributes matching ``**kwargs``. :param base_url: if provided, the generated URL will be appended to it ro re z?%srp r rM i� rN N) rl r9 rf r rr rc rP r2 r r rQ rR )r# re r Zrl�numrT r r r rU e s ��zCrudManager.find)N)N)N)N)r r r r rc rd rf rl rn r r< rL rA ru rF rU r r r r r` � s r` c s8 e Zd ZdZdZdZ� fdd�Zdd� Zdd � Z� Z S ) � ExtensionzExtension descriptor.)Z__pre_parse_args__Z__post_parse_args__Nc s& t t| ��� || _|| _| �� d S rJ )r rw r! �name�module�_parse_extension_module)r# rx ry r$ r r r! � s zExtension.__init__c C s` d | _ | jj�� D ]H\}}|| jv r2| �||� qzt|t�rD|| _ W q tyX Y q0 qd S rJ ) � manager_classry �__dict__rZ �SUPPORTED_HOOKSr � issubclassr r4 )r# � attr_nameZ attr_valuer r r rz � s z!Extension._parse_extension_modulec C s d| j S )Nz<Extension '%s'>)rx rK r r r �__repr__� s zExtension.__repr__) r r r r r} r{ r! rz r� rH r r r$ r rw } s rw c @ s4 e Zd ZdZdd� Zedd� �Zdd� Zdd � Zd S ) �RequestIdMixinz=Wrapper class to expose x-openstack-request-id to the caller.c C s g | _ d S rJ ��x_openstack_request_idsrK r r r �setup� s zRequestIdMixin.setupc C s | j S rJ r� rK r r r � request_ids� s zRequestIdMixin.request_idsc C s: |du r dS t |t�r,|D ]}| �|� qn | �|� dS )zlAdd request_ids as an attribute to the object :param resp: list, Response object or string N)ri rL �_append_request_id)r# r> Zresp_objr r r �append_request_ids� s z!RequestIdMixin.append_request_idsc C s4 t |t�r$|j�d�}| j�|� n | j�|� d S )Nzx-openstack-request-id)ri r �headersr r� r )r# r> Z request_idr r r r� � s z!RequestIdMixin._append_request_idN) r r r r r� �propertyr� r� r� r r r r r� � s r� c @ s� e Zd ZdZdZdZd dd�Zdd� Zed d � �Z d d � Z d d� Z edd� �Z dd� Z dd� Zdd� Zdd� Zdd� Zdd � ZdS ) rj zqBase class for OpenStack resources (tenant, user, etc.).
