It's sad that I have to ask for this, but how can I store a char in my Postgres DB, but show String for the selection of the value. I'm creating a web application with JSF.

So my .xhtml:

<p:outputLabel for="gender" value="Geschlecht:" />
<p:selectOneMenu id="gender" value="#{telefonbuchController.telefonbuch.gender}" style="width:125px">
    <f:selectItem itemLabel="Auswählen" itemValue="" />
    <f:selectItems value="#{telefonbuchController.genderList}" var="c" itemLabel="#{gender}" itemValue="#{gender}"/>
</p:selectOneMenu>

Model:

@Column
private char gender;

In the controller for the form I create a list of Strings for male and female and init them with PostConstruct.

private List<String> geschaeftsstellen;

This

Here you see how it should look. I implemented it with a String, but I want to just store 'm' and 'f' in my database instead of the whole string.

Implement it like this: 

public enum Gender {
MALE('m'),
FEMALE('f')
;

private char shortGender;

public Gender (char shortGender) {
    this.shortGender = shortGender;
}

public char getShortGender() {
    return shortGender;
}

}

And in your template use different values for itemLabel and itemValue, i.e.: 

itemLabel="#{gender}" itemValue="#{gender.shortGender}"

  • Many of these basic jsf things have Q/A with many upvotes. Sorting on votes and reading the, and remember their existence/titles helps a lot. Saves you writing questions! https://stackoverflow.com/questions/8229638/how-to-use-enum-values-in-fselectitems Voting as duplicate instead of answering saves time too ;-) And the company is?

  • How do I store it in the database? I mean I get the error that it cannot convert the type String to class Gender... – CptDayDreamer Jan 28 '19 at 12:19
