Redux Form, Radio Button Fields, how to support variable values?


In my react redux form, I have the following:

        <fieldset className="form-group">
          <legend>Radio buttons</legend>
          {this.props.job_titles.map(jobTitle => (
          <div className="form-check" key={jobTitle.id}>
            <label className="form-check-label">
              <Field
                name="job_title_id"
                component="input"
                type="radio"
                value={jobTitle.id}
              />
              {' '}
              {jobTitle.title}
            </label>
          </div>
          ))}
        </fieldset>

This renders the radio buttons correctly, but when you click to select a radio button, the radio button never sets as selected. You can't select an option - the form is broken.

What's strange is if I update: value={jobTitle.id} to value="anything" then the radio buttons can be selected.

I'm not seeing anything in the redux form docs about radio buttons dynamically generated. What am I doing wrong?

Thanks


Solution

  • Set the checked property to a state or prop, then update that in the click handler.

    <Field
        onClick={
            () => {
                this.setState((prevState) => {
                    return {isChecked: !prevState.isChecked};
                });
            }
        }
        name="job_title_id"
        component="input"
        type="radio"
        checked={this.state.isChecked}
        value={jobTitle.id}
    />
