I too am looking for the answer to this. Moreover, how can I completely remove the excerpt/”read more” function so that each post is shown in its entirety (like one long scrolling blog page that goes through each post without having to click to “read more”)??
i found this, but it appears get_excerpt is being deprecated.

it’s served me well, but i don’t know of a new way to do this.
to get the post to show in its entirety i changed the post type to image instead of standard. don’t know why but that worked for me. i didn’t try the other post types, other formats might have differing results (located to the right of the admin panel when you make a new post). as far as excerpt length i think that is located in the functions but i have not used that feature.
i removed the ‘read more’ link by adding the following to the custom-css file.
/* no more link */
.more-link { display: none; }
to edit css in the presswork theme make a custom-css.css file and add it to the uploads folder. add only your css changes there. that way the css won’t get overwritten when you update wordpress.
