They could use the built in curl to submit a new salary to the controller update method, they could create a script that submits a post with that information.
More than likely it is going to be a field in your database that you don't want anyone monkeying around with. Like a status field, or the like. It is used when you do not have a column in your database, but still want to show a field in your forms.
It will only allow access to the attributes that you specify, denying the rest. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?

See this answer: stackoverflow. This is explained on the offical doc here Rails Model and here Overwriting default accessor scroll down to the chapter "Overwrite default accessor" Say for instance that: we have a database table called "users" that contains three columns "firstname", "lastname" and "role" : SQL instructions : CREATE TABLE users firstname string, lastname string role string ; I assumed that you set the option config.

ARIA: columnheader role The columnheader value of the ARIA role attribute identifies an element as being a cell in a row contains header information for a column, similar to the native th element with column scope. ARIA: combobox role The combobox role is for input that controls another element, such as a listbox or grid, that can dynamically pop up to help the user set the value of the input. ARIA: command role The command role defines a widget that performs an action but does not receive input data.
ARIA: complementary role The complementary landmark role is used to designate a supporting section that relates to the main content, yet can stand alone when separated. These sections are frequently presented as sidebars or call-out boxes.
ARIA: composite role The composite abstract role indicates a widget that may contain navigable descendants or owned children. ARIA: contentinfo role The contentinfo role defines a footer, containing identifying information such as copyright information, navigation links, and privacy statements, found on every document within a site.
This section is commonly called a footer. Dialogs are generally placed on top of the rest of the page content using an overlay. Dialogs can be either non-modal it's still possible to interact with content outside of the dialog or modal only the content in the dialog can be interacted with. ARIA: directory role The directory role was for a list of references to members of a group, such as a static table of contents. ARIA: document role The document role is for focusable content within complex composite widgets or applications for which assistive technologies can switch reading context back to a reading modelement.
ARIA: feed role A feed is a dynamic scrollable list of articles in which articles are added to or removed from either end of the list as the user scrolls. A feed enables screen readers to use the browse mode reading cursor to both read and scroll through a stream of rich content that may continue scrolling infinitely by loading more content as the user reads.
A figure is generally considered to be one or more images, code snippets, or other content that puts across information in a different way to a regular flow of text. ARIA: grid role The grid role is for a widget that contains one or more rows of cells. The position of each cell is significant and can be focused using keyboard input. ARIA: gridcell role The gridcell role is used to make a cell in a grid or treegrid.
It is intended to mimic the functionality of the HTML td element for table-style grouping of information. ARIA: group role The group role can be used for sets of UI feature not intended to be included in a page summary or table of contents by assistive technologies. ARIA: heading role The heading role defines this element as a heading to a page or section, with the aria-level attribute providing for more structure.
These elements could be images, code snippets, text, emojis, or other content that can be combined to deliver information in a visual manner. ARIA: input role The input abstract role is a generic type of widget that allows user input.
ARIA: landmark role A landmark is an important subsection of a page. The landmark role is an abstract superclass for the aria role values for sections of content that are important enough that users will likely want to be able to navigate directly to them. It is normally used in conjunction with the listitem role, which is used to identify a list item contained inside the list. ARIA: listbox role The listbox role is used for lists from which a user may select one or more items which are static and, unlike HTML select elements, may contain images.
It is normally used in conjunction with the list role, which is used to identify a list container. ARIA: log role The log role is used to identify an element that creates a live region where new information is added in a meaningful order and old information may disappear. ARIA: main role The main landmark role is used to indicate the primary content of a document.
The main content area consists of content that is directly related to or expands upon the central topic of a document, or the main function of an application.
This is semantically equivalent to the HTML mark element. If possible, you should use this element instead. ARIA: marquee role A marquee is a type of live region containing non-essential information which changes frequently. ARIA: math role The math role indicates that the content represents a mathematical expression. ARIA: navigation Role The navigation role is used to identify major groups of links used for navigating through a website or page content. An ARIA role attribute can be added to an element to instruct assistive technologies to treat the element as something other than its native HTML element type.
When an assistive technology encounters a mismatch between an element's role and its state or property attributes, it might ignore that attribute or respond in an unexpected way. As a result, people who use assistive technologies might find the element difficult or impossible to use.
