<h2>Introduction<a class="headerlink" href="#introduction" title="Permalink to this headline">¶</a></h2>
|
|
<p>On the server-side, scripts are embedded in DocTypes. All scripts have to reside in classes in the DocTypes.</p>
|
|
<p>To add a server script, open a DocType you want to attach the script to and open the “Server Script” tab.</p>
|
|
<div class="admonition note">
|
|
<p class="first admonition-title">Note</p>
|
|
<p class="last">If you do not want the server script to be attached to any particular DocType, or call it from many
|
|
DocTypes, you can create a “Single” DocType. Then using the get_obj method, you can call it from
|
|
anywhere. More about it later.</p>

<h2>Declaring a Class<a class="headerlink" href="#declaring-a-class" title="Permalink to this headline">¶</a></h2>
|
|
<p>Server Side methods (functions) always reside in a “DocType” class, hence all your DocType classes will
|
|
be declared in the following manner:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="k">class</span> <span class="nc">DocType</span><span class="p">:</span>
|
|
|
|
<span class="c"># standard constructor</span>
|

<span class="k">def</span> <span class="nf">__init__</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">doc</span><span class="p">,</span> <span class="n">doclist</span><span class="p">):</span>
|
|
<span class="bp">self</span><span class="o">.</span><span class="n">doc</span> <span class="o">=</span> <span class="n">doc</span>
|
|
<span class="bp">self</span><span class="o">.</span><span class="n">doclist</span> <span class="o">=</span> <span class="n">doclist</span>
|
|
</pre></div>
|
|
</div>
|
|
<p>Let us see this constructor line by line</p>
|
|
<ol class="arabic simple">
|
|
<li><strong>class DocType</strong> - This is the standard declaration of a class (for any DocType, the class will be labeled DocType)</li>
|
|
<li><strong>def __init__(self, doc, doclist):</strong> - This is the constructor. The object will be constructed by the framework
|
|
and the framework will supply the data record “doc” and a bundle of data-records including child records
|
|
of this object in “doclist”</li>
|
|
<li><strong>self.doc = doc</strong> - Set class property “doc” as the data object</li>
|
|
<li><strong>self.doclist = doclist</strong> - Set the class property “doclist” as the list of child records</li>
|
|
</ol>

</div>
|
|
<div class="section" id="validate-method">
|
|
<h2>validate method<a class="headerlink" href="#validate-method" title="Permalink to this headline">¶</a></h2>
|
|
<p>The validate method is called just before the user saves a record using the “Save” button. To stop the user
|
|
from saving, raise an Exception</p>
|
|
<p>Example:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="k">def</span> <span class="nf">validate</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span>

|
|
<span class="n">msgprint</span><span class="p">(</span><span class="s">'Start date must be before finish date'</span><span class="p">)</span>
|

|
|
<h2>on_update, on_submit, on_cancel methods<a class="headerlink" href="#on-update-on-submit-on-cancel-methods" title="Permalink to this headline">¶</a></h2>
|
|
<p>These methods are called at various stages of saving a document, as defined in <a class="reference external" href="save_submit.html"><em>Save-Submit-Cancel Pattern</em></a></p>
|
|
<p>The on_update method is called after the document values are saved in the database. If you raise an
|
|
Exception in any of these methods, the entire transaction will be rolled back.</p>

<div class="section" id="adding-child-records">
|
|
<h2>Adding Child Records<a class="headerlink" href="#adding-child-records" title="Permalink to this headline">¶</a></h2>
|

<p>Child records can be added on the server side by the addchild method:</p>

<div class="highlight-python"><div class="highlight"><pre><span class="n">addchild</span><span class="p">(</span><span class="n">parent</span><span class="p">,</span> <span class="n">fieldname</span><span class="p">,</span> <span class="n">childtype</span> <span class="o">=</span> <span class="s">''</span><span class="p">,</span> <span class="n">local</span><span class="o">=</span><span class="mi">0</span><span class="p">,</span> <span class="n">doclist</span><span class="o">=</span><span class="bp">None</span><span class="p">)</span>
