Methods
def adaptValSelect(self)-
Adapts the values contained in
valSelectafter a modification action.After the addition or deletion of an entity, the values contained in
valSelectmay have become obsolete or inconvenient for further actions.This function adapts those values before having them rendered on the page.
Parameters
v:dict- Contains the intermediate results of computing the new page.
def findSetup(self)-
Compiles the filter pattern into a regular expression.
When the user enters a search pattern in the box meant to filter the buckets, the pattern will be interpreted as a regular expression.
We do the compilation here. If there are errors in the pattern they will be reported. Whether or not the search is case sensitive or not is under user control, and it will influence the compilation of the pattern.
All input and output data is in
v. def getFormData(self)-
Get form data.
The TF browser user interacts with the app by clicking and typing, as a result of which a HTML form gets filled in. This form as regularly submitted to the server with a request for a new incarnation of the page: a response.
The values that come with a request, must be peeled out of the form, and stored as logical values.
Additionally, some business logic is carried out: we set values for the entity features, based on the form, especially the keys ending in
_active. We build a value under keyvalselectbased on the value for keysubmitter. Depending on which button caused the submit, the NONE value is added to each feature.The idea is that when the user is still engaged in filtering buckets, and there is an occurrence selected, the user should have the option to sub-select occurrences that do not yet have an entity assigned.
def initVars(self)-
Initializes the computation of the new page.
It collects the request data, gleans some info from the configuration settings and the TF app, and initializes some data structures that will collect further information for the page.
All bits and pieces that are needed during processing the request and filling in the final HTML template find a place under some key in the
vdict which is stored inself.So, this function makes the transition from information that is in the
formdictionary to values that are stored in thevdictionary.
